xfomers installation failed

[stevensf1998]

Encountering "ModuleNotFoundError: No module named 'torch'" while running pip install -r requirements.txt.

I have created a venv and selected it as interpreter. Is there any work around or solution for this?

python version : 3.12.3

Hi @stevensf1998, does the issue seem to be with torch or xformers? Could you please post the whole stack trace and also some additional information: linux distro, type of GPUs, cuda version?

I think this happens because xformers installation requires torch to already be installed, though somehow it doesn't seem to be a universal issue. Can you try installing torch first, and then installing requirements.txt?

I have pip install "pip3 install torch torchvision" into my venv. and pip list show that i am installed, but when i run pip3 install -r requirements.txt, it still shows me "No module named 'torch'"

There are some suggestions here that might help. facebookresearch/xformers#740

In particular, maybe try pip3 install wheel before installing requirements.txt.

After installing wheel, i manage to run -r requirements.txt
