I am going through the course. When I am executing the below code cell from [the notebook Introduction to Diffusers using Kaggle](https://www.kaggle.com/code/valmetisrinivas/notebook006d016869/edit), I am getting below indicated error. I am unable to figure out the solution. My HF repository has ‘diffusion\_pytorch\_model.bin’ file. I tried using use\_safetensors = True parameter, tried changing the extension of file to .bin etc., I tried using The discord channels/ messages are not loading up to ask the question; there seems to be some problem with HuggingFace Discord channels [Hugging Face Diffusion Models Course - Hugging Face Diffusion Course](https://huggingface.co/learn/diffusion-course/unit0/1)

Appreciate if someone can help.

```auto
from diffusers import DDPMPipeline

image_pipe = DDPMPipeline.from_pretrained(hub_model_id)
pipeline_output = image_pipe()
pipeline_output.images[0]

```

I just tried it and it also reproduces on Google Colab.😅 You can report a bug below.
