Blender 4.1, Windows, Pallaidium 1.7 (download from today, 11/18) I clicked on install dependencies, but it does not seem to need anything beside what is installed already and throws this error, also when using "Generate"

I notice you use 4.1, I don't know if there is some breaking change/bug, but first try to uninstall dependencies, close Blender, search the HDD for torch, delete if found, restart blender, install dependencies.

It might be a 4.1 thing, so I went back to 4.0 but now I am getting invalid token :((

[gerroon]

Lets not worry about the token, but uninstallinfg dependencies seems to be doing some weird stuff like installing numpy over and over again. Please see the log. Not sure if this is intentional

[gerroon]

Also I uninstalled all the dependencies and reinstalled them using the addon pref, and I still have the same issue.Here is the new log during that

Not sure precisely, but it seems that for me it was solved after installing Cython:
pip3 install Cython

https://github.com/pytorch/pytorch/issues/1633#issuecomment-418237093

[tin2tin]

Try this branch instead - I've tried to do some things about the installation process. Uninstall all dependencies first. Restart, then install this: https://github.com/tin2tin/Pallaidium/tree/Installation_fix

[gerroon]

Thanks I will give it a try. When I initially uninstalled dependencies and reinstalled them, it installed the non CUDA version of torch. I had to manually delete and reinstall it using pip install torch torchvision torchaudio –index-url https:download.pytorch.org/whl/cu118

[tin2tin]

Yeah, it is super frustrating. All of the python module installation is super hit&miss, most of the time it just does something unexpected, properly due pip is backing up old modules and also keep them as temp files, so it takes a lot of effort to get rid of a failing module.

[tin2tin]

I've updated the main code with the changes from the fork. Let me know if it solves your problems, so I can close this report if it does.

[tin2tin]

I installed https://pinokio.computer/ and that actually caused that error. So, now I uninstalled it, and try to remove all the stuff it installed on my machine, and then reinstall all Pallaidium dependencies. I hope this solves it.

My guess is that it is a bug in a specific version of Torch, so try to search all of your hard disk and delete all torch-related folders, and install dependencies.

[gerroon]

I had issues with cpu version of torch installed with other AI apps too. This pip install torch torchvision torchaudio –index-url https:download.pytorch.org/whl/cu118 generally fixes it once the old toch removed like you said.

[tin2tin]

This is basically pip hiding the module everywhere when you try to uninstall it: https://youtu.be/YtfQLyy43Xg?si=ImteCbsfLuYAOnim&t=788 which means you'll get into trouble when you try to change the version.

[tin2tin]

Thank you. Closing.
