How to re-run the google collab program?

[hbirchwright]

I followed the steps in the tutorial for the AUTOMATIC1111 google collab web server for stable diffusion. I ran the site one time successfully, but when I went back after closing it, it stopped working. When I try and start it again I get the following error:

Traceback (most recent call last):
File "/content/gdrive/MyDrive/sd/stable-diffusion-webui/webui.py", line 83, in
shared.sd_model = modules.sd_models.load_model()
File "/content/gdrive/MyDrive/sd/stable-diffusion-webui/modules/sd_models.py", line 182, in load_model

File "/content/gdrive/MyDrive/sd/stable-diffusion-webui/modules/sd_models.py", line 137, in load_model_weights
pl_sd = torch.load(checkpoint_file, map_location="cpu")

magic_number = pickle_module.load(f, **pickle_load_args)
_pickle.UnpicklingError: could not find MARK

What does this mean and how can I get it working again?

Are you using this colab : https://colab.research.google.com/github/TheLastBen/fast-stable-diffusion/blob/main/fast_stable_diffusion_AUTOMATIC1111.ipynb

I'm using a copy of it.

You need the latest update, get it from the main page of the repo

That seems to have fixed it. Thanks!
