Error while installing OpenOutpaint extensions on A1111 on Colab

[i-huzaifa-arshad]

So, I just saw a post on Reddit about A1111 that it now have an extension "OpenOutpaint". I tried installing it in your A1111 Colab, but getting this error. Can you please go through this issue? So I can enjoy this. Thanks.

Error running install.py for extension /content/gdrive/MyDrive/sd/stable-diffusion-webui/extensions/openOutpaint-webUI-extension.
Command: "/usr/bin/python3" "/content/gdrive/MyDrive/sd/stable-diffusion-webui/extensions/openOutpaint-webUI-extension/install.py"

I'll check it out, even after the fix you will probably get the "launch" error, just ignore it.

Alright. Looking forward to your kind response sir.

Hi, @TheLastBen! I guess you have already given this issue a look, but I will give here a compiled version of the results of an investigation on our side regarding installing some extensions to the colab's notebook! (That thread is quite long after all)

Firstly, this seems to mostly be an issue with extensions that require an install.py script, such as dreambooth, dreamartist and of course our openOutpaint-webUI extensions, which fail to include the base modules launch.py and modules.py from stable-diffusion-webui's root. Other extensions that do not need to import local webui files do not seem to be affected, mostly.

From more searching, we found out the errors were due to the assumption from the webui, when running extensions, that the current working directory (cwd) was being set to the webui's root. The cwd, when running the webui.py command, was, though, the main stablediffusion directory, not the webui's. Noticing that, we added a simple %cd /content/gdrive/MyDrive/sd/stable-diffusion-webui to the end of the "Start stable-diffusion" cell, just before running python3 webui, and that seems to have fixed all extension compatibility issues we were experiencing. (Including dreambooth and dreamartist)

I do not know if this is the optimal solution for this problem, or if any more colab specificities should be considered, but it seems running the webui should be done while on the webui's root as a working directory. If there is any more information you would like, I will promptly provide them!

And great notebook, by the way! Already recommended it to some of my friends!

@zaif24, for now, adding this %cd line should be an okay temporary fix for this problem. Remember to enable the API flag as well if using openOutpaint!

Thanks Seijihariki for looking into this. I have not been able to get several of the extensions to work (colab) so I look forward trying this.
