The main advantages of precompiling chunks are: faster loading, protecting source code from user changes, and off-line syntax checking.
Pre-compiling does not imply faster execution because in Lua chunks are always compiled into bytecodes before being executed. luac simply allows those bytecodes to be saved in a file for later execution.
luac produces a single output file containing the bytecodes for all source files given. By default, the output file is named luac.out, but you can change this with the -o option.
The binary files created by luac are portable to all architectures with the same word size. This means that binary files created on a 32-bit platform (such as Intel) can be read without change in another 32-bit platform (such as Sparc), even if the byte order (``endianness'') is different. On the other hand, binary files created on a 16-bit platform cannot be read in a 32-bit platform, nor vice-versa.
In the command line, you can mix text files containing Lua source and binary files containing precompiled chunks. This is useful to combine several precompiled chunks, even from different (but compatible) platforms, into a single precompiled chunk.
You can use "-" to indicate the standard input as a source file and "--" to signal the end of options (that is, all remaining arguments will be treated as files even if they start with "-").
The internal format of the binary files produced by luac is likely to change when a new version of Lua is released. So, save the source files of all Lua programs that you precompile.
-l produce a listing of the compiled bytecode for Lua's virtual machine. Listing bytecodes is useful to learn about Lua's virtual machine. If no files are given, then luac loads luac.out and lists its contents.
-o "file" output to file, instead of the default luac.out. The output file may be a source file because all files are loaded before the output file is written. Be careful not to overwrite precious files.
-p load files but do not generate any output file. Used mainly for syntax checking and for testing precompiled chunks: corrupted files will probably generate errors when loaded. Lua always performs a thorough integrity test on precompiled chunks. Bytecode that passes this test is completely safe, in the sense that it will not break the interpreter. However, there is no guarantee that such code does anything sensible. (None can be given, because the halting problem is unsolvable.) If no files are given, then luac loads luac.out and tests its contents. No messages are displayed if the file passes the integrity test.
-s strip debug information before writing the output file. This saves some space in very large chunks, but if errors occur when running these chunks, then the error messages may not contain the full information they usually do (line numbers and names of locals are lost).
-v show version information.

James Michael, 32, contracted schistosomiasis - also known as bilharzia - during his dream Africa trip.

"It wasn't exactly how I imagined the trip of a lifetime to go...the whole experience was surreal and strange."
The 32-year-old had visited Africa with three friends in August 2017. They traveled from Zambia to Zimbabwe before visiting Malawi for five days.
MAN HAS 12-CENTIMETER PARASITIC WORM REMOVED FROM BRAIN AFTER YEARS OF NUMBNESS, BLACKOUTS
The group swam and canoed every day on Lake Malawi, before flying back to the UK.
It was back in England that James' nightmare began.
In October last year, he started to notice a loss of feeling in both his legs - but initially put that down to fatigue from cycling.
But he checked himself into hospital when basic tasks like climbing the stairs to his flat became exhausting.
James was given antibiotics and sent home but, a week later, he felt even worse and so returned to Chelsea and Westminster Hospital.
PARASITE IN FRESHWATER SNAILS LIKELY CAUSED MAN'S CALCIFIED BLADDER
"I explained to them that something serious was going on"— James Michael told hospital staff after his Africa trip.
He said: "I explained to them that something serious was going on.
"I went to the neurology department and they did blood tests to see what was up. They determined quite quickly that my immune system was attacking my spine, leading to the loss of control of my legs.
"I was put on a six-month course of steroids to counter this...but they didn't actually know what had caused this."

A week before Christmas he was diagnosed with schistosomiasis, an infection that's caused by a parasitic worm that lives in fresh water in tropical regions. It's most commonly found throughout Africa.
Once in the body, the worms move through the blood to areas such as the liver and bowel. After a few weeks, they start to lay eggs.
Some eggs remain inside the body and are attacked by the immune system. If it's left untreated it could have severe consequences.
James was prescribed a medication called praziquantel that kills the worms.
He said: "That killed the infection but I was left basically debilitated. They told me there was a 30 percent chance I'd make a full recovery - 10 years from now.

"It was a horrible feeling - I felt completely helpless, and the odds weren't good. I couldn't wish what I've been through on anybody."
James spent a total of three months in the hospital using a wheelchair and then four months on crutches - until April this year.
He also had a breakout of extreme acne on his back and arms caused by steroids, as well as diarrhea.
He said: "The pain has been like nothing I've ever known.
"Early in my recovery, sometime in January, I had a really terrible acne outbreak that went all down my back and down my arms.

"I couldn't sleep for a month because lying on my back hurt. I couldn't really be under running water either, so I had to shower my front instead.
"The loss of feeling and use of my legs affected every part of my life. I wasn't able to exercise much because of the infection, which was hard.

14 April 1997
Disease Outbreak Reported
Following reports of ongoing cases of human monkeypox in Zaire representing a new pattern of the disease, the Ministry of Health in Zaire and the World Health Organization (WHO) organized an investigation in February 1997. Monkeypox, a disease which closely resembles smallpox, is preventable by the vaccination against smallpox.
The study revealed that this outbreak represents the largest cluster of monkeypox cases ever reported, and the proportion of patients that were 15 years of age or older (27%) was higher than previously reported (8%). Young children have been most affected in previous outbreaks. These findings contradict previously accepted findings on the nature of the disease.
Studies over a twenty year period have shown that the rate of transmission of monkeypox within households was low, suggesting that the disease had a low potential for transmission from person to person and that an outbreak could not last long after the first patients recovered. However, the recent study has shown that active cases in February 1997 were linked to cases that occurred during the preceding 12 month period. The study also revealed the following:
The rate of transmission from person to person (73%) was higher than previously reported (30%). This was associated with the clustering of cases in household compounds and prolonged chains of transmission from person to person.
The proportion of deaths (3%) was lower than previously reported (10%).
Monkeypox disease closely resembles ordinary forms of smallpox. The viruses causing the two diseases are related and vaccination against smallpox also protects against monkeypox. The emergence of monkeypox does not mean that smallpox, which has been eradicated, is re-emerging.
All age groups are affected, but children who have not been vaccinated are at the highest risk of death, about a 10% case fatality rate. Most cases occur in remote villages of Central and West Africa close to tropical rainforests where there is frequent contact with infected animals. Monkeypox is usually transmitted to humans from squirrels and primates.
In the past, an outbreak of monkeypox would not go very far in the village or last long because it did not spread extensively after the first patients recovered. However, what concerns WHO is that the present study indicates that monkeypox disease is changing its pattern of infection in humans. This outbreak has a much higher rate of person-to-person transmission than seen before, and spread through many generations of transmission, thus maintaining the outbreak for more than a year.
The ending of vaccination programmes against smallpox in the late 1970's has probably led to an increase in susceptibility to monkeypox and could explain the larger size of the outbreak, the higher proportion of patients aged 15 and over, and the spread through many generations of transmission.
The changing nature of monkeypox disease is of concern to WHO. In the past, before the eradication of smallpox in 1980, smallpox vaccination was widespread and protected against both smallpox and monkeypox. Since the eradication of smallpox, vaccination programmes have been discontinued as recommended by WHO and WHO is concerned that monkeypox could pose a localized public health problem. WHO will therefore continue to maintain vigilance by strengthening detection systems for monkeypox and completely investigating future outbreaks so that the best strategy for prevention and control may be developed.
Articles describing the investigation will simultaneously appear on 11April 1997, in the WHO Weekly Epidemiological Record, in the U.S. Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report, and in the next edition of Eurosurveillance. In addition to WHO the study partners were from: Centers for Disease Control and Prevention, Institut national de Recherche biomédicale, Kinshasa; Ecole de Santé publique, Kinshasa; the European Programme for Intervention Epidemiology Training (EPIET), Brussels; and Médicins Sans Frontières.

If you're displaying a PDF file from a REST API, you often receive it as a BLOB. You can simply use the src
attribute to display the BLOB. Since version 6.0.0, you can use this feature with a strict Content Security Policy strictly
(see this issue for details).
This demo uses a file that's already in memory and a file that finishes loading after the PDF viewer has initialized. That's no difference from a programmers perspective, but it results in a different internal data flow, so both options are shown.
You can also download the PDF file as a BLOB. For instance, the user can upload a file, and you can use the method
NgxExtendedPdfViewerService.getCurrentDocumentAsBlob()
to send the file to your server. Or the user
can fill a form embedded in the PDF file, and you can download the file containing the user's input.

Field experiment: Conduct an A/B test for individual ad targeting (target a set of people we think are likely to purchase and EV and a set of random people and compare click rates among both groups; ideally the click rate would be higher for our targeted group compared to the random group). This could also help validate the power of the models.
Look at dates of EV stations opening and determine which locations are growing fastest (time series analysis), take this into account in our predictive models

Well, it was a good run; I think I’ve written at least one post every weekday since the first week in January—a first for me. I have a new respect for those bloggers who post great content, day after day. It’s hard work!
Unfortunately, I’m going to be doing some traveling late next week, and so I’ll be taking the week off from posting to this blog. Recharging my batteries, so to speak. Expect more posts (hopefully I can keep up this daily schedule!) beginning on Monday the 19th.
Thank-you to all of you who have written in with suggestions of things to write about. I’ll be going over those suggestions this next week, and will possibly write up one or two of them. If anyone else has ideas, please feel free to post them in the comments here.

Despite Hollywood's depiction of 'hackers' as those who steal millions from unsuspecting citizens or launch cyberattacks on governments, hackathons are actually productive (and not illegal!). Hackathons center on collaboration between computer programmers, designers, and other creative people to solve problems and prototype new ideas. While aggravated assault on Xerox machines is not unheard of, hackers at hackathons are helpful members of society.
The Stevens Venture Center seeks to redefine entrepreneurial education and support rising student entrepreneurs. To kick it all off, the Stevens Venture Center is hosting its first ever hackathon, Venture Hacks, where we’ll bring 30 of Stevens' brightest students together for a weekend of building, designing, and collaborating on real problems in our community.
Since the Venture Center is located in the heart of Hoboken, we'd like to focus our efforts on
improving our community and solving some of the toughest issues about living here. So, what bugs
you about Hoboken? Is your daily commute a struggle? Does something about the waterfront bother
you? How about the parks? Housing? Transportation? Finding places to eat? Anything on your mind?

I'm a SWE in Google Health. I'm interested in building web apps, coding videogames, and teaching / tutoring (both coding and non-coding things!).
I have previous experience both in industry as well as in research roles. For example, I've previously interned at Amazon, Microsoft, IBM and Morgan Stanley. Also, I was an undergraduate researcher at MIT D-Lab in the Mobile Technology Group.
Please see my resume (or continue scrolling down here) if you want to learn more about my past positions.
Above all, I am passionate about altruistic causes using technology. For example, at MIT, I served on the exec team of Code for Good Consulting, a club
that works with teams of MIT students to code and deliver pro-bono software-driven solutions to local nonprofits. Also, I mentored for MIT CodeIt (a weekly programming class at MIT for middle school girls and nonbinary students)
and was an instructor for Patrones Hermosos (a program for which we traveled to Aguascalientes, Mexico and taught high school girls computer science fundamentals, including web development, cryptography,and basic algorithms).
Finally, my research for MIT D-Lab went towards deploying a server that makes it easier for patients with pulmonary disease or diabetes
in rural parts of Southeast Asia to get diagnoses and treatment.
In my free time, I enjoy working out, singing (check out my a cappella group's videos here), traveling, puzzle hunting, playing board games, and watching cat videos :)

1 Then I saw a beast coming up out of the sea. He had ten horns and seven heads. On his horns were ten crowns, and on his heads were names that were insulting to God.
2 This beast I saw was like a leopard.  The dragon gave his power to him, and his throne, and his great authority to rule.
3 One of the beast's heads appeared to have a lethal wound that would have caused his death. But that wound had been healed, and the whole earth marveled and followed the beast.
4 They also worshiped the dragon, for he had given his authority to the beast. They worshiped the beast, too, and kept saying, "Who is like the beast? and "Who can fight against him?"
5 The beast was given a mouth that could speak proud words and insults. He was permitted to exercise authority for forty-two months.
6 So the beast opened his mouth to speak insults against God, insulting his name, the place where he lived, and those who live in heaven.
7 The beast was permitted to make war with the holy people and to conquer them. Also, authority was given to him over every tribe, people, language, and nation.
8 All who live on the earth will worship him, everyone whose name was not written, since the creation of the world, in the book of life, that belongs to the Lamb, who was slaughtered.
9 If anyone has an ear, let him listen.
10 If anyone is to be taken into captivity,
into captivity he will go.
If anyone is to be killed with a sword,
with a sword he will be killed.
Here is a call for patient endurance and faith for those who are holy.
11 Then I saw another beast coming up out of the earth. He had two horns like a lamb and he spoke like a dragon.
12 He exercised all the authority of the first beast in his presence, and made the earth and those who live on it worship the first beast—the one whose lethal wound had been healed.
13 He performed mighty miracles, even making fire come down on the earth from heaven in front of people,
14 and by the signs he was permitted to do, he deceived those who lived on the earth, telling them to make an image in honor of the beast who was wounded by the sword, but still he lived.
15 He was permitted to give breath to the image of the beast so that the image might even speak and to cause all who refused to worship the beast to be killed.
16 He also forced everyone, unimportant and mighty, rich and poor, free and slave, to receive a mark on the right hand or on the forehead.
17 It was impossible for anyone to buy or sell unless he had the mark of the beast, that is, the number representing his name.
18 This calls for wisdom. If anyone has insight, let him calculate the number of the beast. For it is the number of a human being. His number is 666.

Description
The sozip utility can be used to:
create a SOZip (Seek-Optimized ZIP) file
append files to an existing ZIP/SOZip file
list the contents of a ZIP/SOZip file
validate a SOZip file
convert an existing Zip file in a SOZip optimized one
- --quiet
Quiet mode. No progress message is emitted on the standard output.
- --verbose
Verbose mode.
- -g
- --grow
Grow an existing zip file with the content of the specified filename(s). This is the default mode of the utility. This switch is here for compatibility with Info-ZIP zip utility
- --overwrite
Overwrite the target zip file if it already exists.
- -l
- --list
List the files contained in the zip file in an output similar to Info-ZIP unzip utility, but with the addition of a column indicating whether each file is seek-optimized.
- --validate
Validates a SOZip file. Baseline ZIP validation is done in a light way, limited to being able to browse through ZIP records with the InfoZIP-based ZIP reader used by GDAL. But validation of the SOZip-specific aspects is done in a more thoroughful way.
- -j
- --junk-paths
Store just the name of a saved file (junk the path), and do not store directory names. By default, sozip will store the full path (relative to the current directory).
- --optimize-from=<input.zip>
Re-process {input.zip} to generate a SOZip-optimized .zip. Options
--enable-sozip
,--sozip-chunk-size
and--sozip-min-file-size
may be used in that mode.
- --enable-sozip=auto/yes/no
In
auto
mode, a file is seek-optimized only if its size is above the value of--sozip-chunk-size
. Inyes
mode, all input files will be seek-optimized. Inno
mode, no input files will be seek-optimized.
- --sozip-chunk-size
Chunk size for a seek-optimized file. Defaults to 32768 bytes. The value is specified in bytes, or K and M suffix can be respectively used to specify a value in kilo-bytes or mega-bytes.
- --sozip-min-file-size
Minimum file size to decide if a file should be seek-optimized, in --enable-sozip=auto mode. Defaults to 1 MB byte. The value is specified in bytes, or K, M or G suffix can be respectively used to specify a value in kilo-bytes, mega-bytes or giga-bytes.
- --content-type=<value>
Store the Content-Type for the file being added as a key-value pair in the extra field extension 'KV' (0x564b) dedicated to storing key-value pair metadata
- <zip_filename>
Filename of the zip file to create/append to/list.
- <filename>
Filename of the file to add.
Multithreading
The GDAL_NUM_THREADS
configuration option can be set to
ALL_CPUS
or a integer value to specify the number of threads to use for
SOZip-compressed files. Defaults to ALL_CPUS
.
C API
Functionality of this utility can be done from C with CPLAddFileInZip()
or VSICopyFile()
.
Examples
Create a, potentially seek-optimized, ZIP file with the content of my.gpkg:
sozip my.gpkg.zip my.gpkg
Create a, potentially seek-optimized, ZIP file from the content of a source directory:
sozip -r my.gpkg.zip source_dir/
Create a, potentially seek-optimized, ZIP file from an existing ZIP file.
sozip --convert-from=in.zip out.zip
List the contents of a ZIP file and display which files are seek-optimized:
sozip -l my.gpkg.zip
Validates a SOZip file:
sozip --validate my.gpkg.zip


New York, Richmond, Kings, Queens, and Bronx Counties, NY
Missing months in Phoenix are due to data unavailability. Monthly median claim amounts in New York City for April, May, and June were omitted due to low case counts (3, 4, and 10 respectively), a function of a strict state-level eviction moratorium.
These block groups contain 31.4% of renter households and 17.3% of the overall population in Harris County.
Eviction filings in these block groups made up 43% of all Harris County filings in November.

This package provides a full thermodynamic model of moist air including the fog region and temperatures below zero degC. The governing assumptions in this model are:
All extensive properties are expressed in terms of the total mass in order to comply with other media in this library. However, for moist air it is rather common to express the absolute humidity in terms of mass of dry air only, which has advantages when working with charts. In addition, care must be taken, when working with mass fractions with respect to total mass, that all properties refer to the same water content when being used in mathematical operations (which is always the case if based on dry air only). Therefore two absolute humidities are computed in the BaseProperties model: X denotes the absolute humidity in terms of the total mass while x denotes the absolute humidity per unit mass of dry air. In addition, the relative humidity phi is also computed.
At the triple point temperature of water of 0.01 °C or 273.16 K and a relative humidity greater than 1 fog may be present as liquid and as ice resulting in a specific enthalpy somewhere between those of the two isotherms for solid and liquid fog, respectively. For numerical reasons a coexisting mixture of 50% solid and 50% liquid fog is assumed in the fog region at the triple point in this model.
From the assumptions mentioned above it follows that the
pressure should be in the region around
atmospheric conditions or below (a few bars may
still be fine though). Additionally a very high water content at
low temperatures would yield incorrect densities, because the
volume of the liquid or solid phase would not be negligible
anymore. The model does not provide information on limits for water
drop size in the fog region or transport information for the actual
condensation or evaporation process in combination with surfaces.
All excess water which is not in its vapour state is assumed to be
still present in the air regarding its energy but not in terms of
its spatial extent.
The thermodynamic model may be used for
temperatures ranging from 190 ... 647
K. This holds for all functions unless otherwise stated in
their description. However, although the model works at
temperatures above the saturation temperature it is questionable to
use the term "relative humidity" in this region. Please note, that
although several functions compute pure water properties, they are
designed to be used within the moist air medium model where
properties are dominated by air and steam in their vapor states,
and not for pure liquid water applications.
Several additional functions that are not needed to describe the thermodynamic system, but are required to model transport processes, like heat and mass transfer, may be called. They usually neglect the moisture influence unless otherwise stated.
The model's main area of application is all processes that involve moist air cooling under near atmospheric pressure with possible moisture condensation. This is the case in all domestic and industrial air conditioning applications. Another large domain of moist air applications covers all processes that deal with dehydration of bulk material using air as a transport medium. Engineering tasks involving moist air are often performed (or at least visualized) by using charts that contain all relevant thermodynamic data for a moist air system. These so called psychrometric charts can be generated from the medium properties in this package. The model PsychrometricData may be used for this purpose in order to obtain data for figures like those below (the plotting itself is not part of the model though).

Maestro Nikola:
Work together? Undoubtedly she has made some minor strides in her studies that might possibly be of use to me, but...
My pride would never allow me to conclude some sort of agreement with her. In fact, I can barely stand to even speak to her!
Unfortunate, perhaps...
"Perhaps you could enter into a contract with me, not with her. Then I will also make a separate contract with her. With me as a go-between you won't have to deal directly with each other."

On a daily basis our customers and community ask us to recommend a sensor provider to buy from, you should ping me on<EMAIL_ADDRESS>if you want us to recommend your sensor. Often the requirement is vague, “I need an air quality sensor to put on my street for $100?” or “What sensors shall I use to understand my space usage?”. My process of assessment has grown more refined over time because if the sensors we recommend are unsuitable or unusable our company’s reputation is also on the line by association.
So we have come up with our own unscientific way to rate the quality of a sensor that should be applied simply. Most large scale sensor rollout projects of 1K or more often have these requirements as well. It’s possible that sensor providers that don’t rate highly using our criteria produce good sensors but getting the below right takes iteration and discipline in design and the likelihood is that the provider will a higher chance of being able to deliver.
Battery life If a sensor is battery powered, the typical expected life of battery should be clearly stated. Buyers will often want some explanation of what typical means for your sensor i.e. if it’s a PIR sensor have you calculated battery life based on being triggered once a day? The last thing your customers wants to do is invest in a lot of sensors, plus the cost of installation in order to find out that the battery life is only % of what they expected as it will still cost them a lot of money to rip them out and return them.
Bonus point for sensors that publish their battery status as standard so that the sensor owners can have some warning before changing.
Heartbeats
Sensors should tell people whether they are still alive or not periodically. Depending on your battery and connectivity constraints, this can vary, the important thing is that the buyer should not find out a bunch of devices are not working because they haven’t been heard from in days or weeks. Top tip; Heartbeats every 10-60 minutes when possible is sufficient, anymore and it ceases to be informative.
Installation and maintenance procedure
In non consumer environments, the people installing and maintaining sensors are often not the technical design firms or manufacturers. Does your device clearly tell people how to install it, do you have helper applications so that they don’t have to configure firmware? We are working on some solutions for this but more on this later; hint it’s all about enabling people to install sensors efficiently and a non technical installer being able to walk away knowing that the device has joined the network correctly. Does your sensor come with mounting and fittings?
Do people have to unscrew the casing to change batteries? Have you tested this with people and verified it?
Data Quality
Quality in my definition means, is the data from your sensor easily understandable for someone that doesn’t know your domain. The reality is that often manufacturers pass on the analogue value of the particular sensor and that is too low of an abstraction for most people trying to read it. Battery voltage is a good example, during its life an AA battery will go from 1.5v to about 0.8v, but it follows a curve specific to the device and the battery. Understanding how this maps to a percentage or days of life is often complex. If it’s not possible to do much conversions or processing on your sensor or gateway, perhaps a handy explainer when people buy your device making them understand what the data means.
Support
Please state clear terms for warranties and return procedures to protect your consumers. Consumer protection should naturally apply.
Finally developing high quality hardware is hard, I am always amazed at the skill and dedication it takes when hardware designers and engineers take an idea and get it to manufacturing stage. We try to manage the community’s expectations on sensors they should buy vs the attitude of ‘just throw around cheap sensors’. It would be better in terms of environmental sustainability and user experience to get into the habit of doing more with less sensor density. For more on this, see Dr Boris Adryan’s excellent blog post
I have purposefully not mentioned security in this post as security assessments come with a lot of complexity, will aim to write up on this sometime soon.
Many Thanks to Toby Jaffey for editing.

I'm Yimin Yan, currently studying Computer Science and Management Information Systems at
The University of Georgia, graduating in Fall 2020:)
Being a bulldawg in the past a few years, I had so much fun and great moments in both academic and extracurricular
life as an international student who came from China. Life wasn't easy at the beginning because of culture shock
and some other barriers. However, all those experiences has become invaluable and has helped me grow.
As a senior student doing a double major in CS&MIS, I'm very interested in technology-related concepts such as NLP, robotics etc.
Meanwhile, I'm non-stop seeking opportunities that can help expose me more on those fileds such as Software Engineering, Technical Consulting etc.
and idealy if knowledge from both majors can be applied.

Installation guide¶
Installing Scrapy¶
Scrapy runs on Python 2.7 and Python 3.4 or above under CPython (default Python implementation) and PyPy (starting with PyPy 5.9).
If you’re using Anaconda or Miniconda, you can install the package from the conda-forge channel, which has up-to-date packages for Linux, Windows and OS X.
To install Scrapy using conda
, run:
conda install -c conda-forge scrapy
Alternatively, if you’re already familiar with installation of Python packages, you can install Scrapy and its dependencies from PyPI with:
pip install Scrapy
Note that sometimes this may require solving compilation issues for some Scrapy dependencies depending on your operating system, so be sure to check the Platform specific installation notes.
We strongly recommend that you install Scrapy in a dedicated virtualenv, to avoid conflicting with your system packages.
For more detailed and platform specifics instructions, as well as troubleshooting information, read on.
Things that are good to know¶
Scrapy is written in pure Python and depends on a few key Python packages (among others):
- lxml, an efficient XML and HTML parser
- parsel, an HTML/XML data extraction library written on top of lxml,
- w3lib, a multi-purpose helper for dealing with URLs and web page encodings
- twisted, an asynchronous networking framework
- cryptography and pyOpenSSL, to deal with various network-level security needs
The minimal versions which Scrapy is tested against are:
- Twisted 14.0
- lxml 3.4
- pyOpenSSL 0.14
Scrapy may work with older versions of these packages but it is not guaranteed it will continue working because it’s not being tested against them.
Some of these packages themselves depends on non-Python packages that might require additional installation steps depending on your platform. Please check platform-specific guides below.
In case of any trouble related to these dependencies, please refer to their respective installation instructions:
Using a virtual environment (recommended)¶
TL;DR: We recommend installing Scrapy inside a virtual environment on all platforms.
Python packages can be installed either globally (a.k.a system wide), or in user-space. We do not recommend installing scrapy system wide.
Instead, we recommend that you install scrapy within a so-called
“virtual environment” (virtualenv).
Virtualenvs allow you to not conflict with already-installed Python
system packages (which could break some of your system tools and scripts),
and still install packages normally with pip
(without sudo
and the likes).
To get started with virtual environments, see virtualenv installation instructions. To install it globally (having it globally installed actually helps here), it should be a matter of running:
$ [sudo] pip install virtualenv
Check this user guide on how to create your virtualenv.
Note
If you use Linux or OS X, virtualenvwrapper is a handy tool to create virtualenvs.
Once you have created a virtualenv, you can install scrapy inside it with pip
,
just like any other Python package.
(See platform-specific guides
below for non-Python dependencies that you may need to install beforehand).
Python virtualenvs can be created to use Python 2 by default, or Python 3 by default.
- If you want to install scrapy with Python 3, install scrapy within a Python 3 virtualenv.
- And if you want to install scrapy with Python 2, install scrapy within a Python 2 virtualenv.
Platform specific installation notes¶
Windows¶
Though it’s possible to install Scrapy on Windows using pip, we recommend you to install Anaconda or Miniconda and use the package from the conda-forge channel, which will avoid most installation issues.
Once you’ve installed Anaconda or Miniconda, install Scrapy with:
conda install -c conda-forge scrapy
Ubuntu 14.04 or above¶
Scrapy is currently tested with recent-enough versions of lxml, twisted and pyOpenSSL, and is compatible with recent Ubuntu distributions. But it should support older versions of Ubuntu too, like Ubuntu 14.04, albeit with potential issues with TLS connections.
Don’t use the python-scrapy
package provided by Ubuntu, they are
typically too old and slow to catch up with latest Scrapy.
To install scrapy on Ubuntu (or Ubuntu-based) systems, you need to install these dependencies:
sudo apt-get install python-dev python-pip libxml2-dev libxslt1-dev zlib1g-dev libffi-dev libssl-dev
python-dev
,zlib1g-dev
,libxml2-dev
andlibxslt1-dev
are required forlxml
libssl-dev
andlibffi-dev
are required forcryptography
If you want to install scrapy on Python 3, you’ll also need Python 3 development headers:
sudo apt-get install python3 python3-dev
Inside a virtualenv,
you can install Scrapy with pip
after that:
pip install scrapy
Note
The same non-Python dependencies can be used to install Scrapy in Debian Jessie (8.0) and above.
Mac OS X¶
Building Scrapy’s dependencies requires the presence of a C compiler and development headers. On OS X this is typically provided by Apple’s Xcode development tools. To install the Xcode command line tools open a terminal window and run:
xcode-select --install
There’s a known issue that
prevents pip
from updating system packages. This has to be addressed to
successfully install Scrapy and its dependencies. Here are some proposed
solutions:
(Recommended) Don’t use system python, install a new, updated version that doesn’t conflict with the rest of your system. Here’s how to do it using the homebrew package manager:
Install homebrew following the instructions in https://brew.sh/
Update your
PATH
variable to state that homebrew packages should be used before system packages (Change.bashrc
to.zshrc
accordantly if you’re using zsh as default shell):echo "export PATH=/usr/local/bin:/usr/local/sbin:$PATH" >> ~/.bashrc
Reload
.bashrc
to ensure the changes have taken place:source ~/.bashrc
Install python:
brew install python
Latest versions of python have
pip
bundled with them so you won’t need to install it separately. If this is not the case, upgrade python:brew update; brew upgrade python
(Optional) Install Scrapy inside an isolated python environment.
This method is a workaround for the above OS X issue, but it’s an overall good practice for managing dependencies and can complement the first method.
virtualenv is a tool you can use to create virtual environments in python. We recommended reading a tutorial like http://docs.python-guide.org/en/latest/dev/virtualenvs/ to get started.
After any of these workarounds you should be able to install Scrapy:
pip install Scrapy
PyPy¶
We recommend using the latest PyPy version. The version tested is 5.9.0. For PyPy3, only Linux installation was tested.
Most scrapy dependencides now have binary wheels for CPython, but not for PyPy.
This means that these dependecies will be built during installation.
On OS X, you are likely to face an issue with building Cryptography dependency,
solution to this problem is described
here,
that is to brew install openssl
and then export the flags that this command
recommends (only needed when installing scrapy). Installing on Linux has no special
issues besides installing build dependencies.
Installing scrapy with PyPy on Windows is not tested.
You can check that scrapy is installed correctly by running scrapy bench
.
If this command gives errors such as
TypeError: ... got 2 unexpected keyword arguments
, this means
that setuptools was unable to pick up one PyPy-specific dependency.
To fix this issue, run pip install 'PyPyDispatcher>=2.1.0'
.
Troubleshooting¶
AttributeError: ‘module’ object has no attribute ‘OP_NO_TLSv1_1’¶
After you install or upgrade Scrapy, Twisted or pyOpenSSL, you may get an exception with the following traceback:
[…]
File "[…]/site-packages/twisted/protocols/tls.py", line 63, in <module>
from twisted.internet._sslverify import _setAcceptableProtocols
File "[…]/site-packages/twisted/internet/_sslverify.py", line 38, in <module>
TLSVersion.TLSv1_1: SSL.OP_NO_TLSv1_1,
AttributeError: 'module' object has no attribute 'OP_NO_TLSv1_1'
The reason you get this exception is that your system or virtual environment has a version of pyOpenSSL that your version of Twisted does not support.
To install a version of pyOpenSSL that your version of Twisted supports,
reinstall Twisted with the tls
extra option:
pip install twisted[tls]
