Wrong pytorch

[Creepybits]

I'm sorry if this question isn't supposed to go here, but I'll give it a go.

I had PyTorch 2.1.2+cu121 installed and got a warning saying that

xFormers can't load C++/CUDA extensions. xFormers was built for: PyTorch 2.2.1+cu121 with CUDA 1201 (you have 2.1.2+cu121)

So I uninstalled it and did a clean install of PyTorch 2.2.1+cu121, and instead get the message:
xFormers can't load C++/CUDA extensions. xFormers was built for: PyTorch 2.1.2+cu121 with CUDA 1201 (you have 2.2.1+cu121)

That doesn't seem fair at all!

And on top of it all I get an error message saying that "procedure" something issues with

?requires_grad@TensorOptions@c10@@QEBA?AU12@V?$optional@_N@2@@Z

at

\AppData\Local\Programs\Python310\Lib\site-packagees\xformers_C.pyd

I have no idea what any of this means, and I cant seem to fix it no matter what, I'm sure it's probably something super easy, but I don't have any knowledge at all in this area

Hi,
How did you install Xformers and PyTorch originally?
I would try to uninstall Xformers and reinstall it with:

pip uninstall -y xformers torch
pip install -U xformers torch --index-url https://download.pytorch.org/whl/cu121

Im not 100% sure, but most likely they got installed together with Automatic1111

I tried your suggestion, it didn't make any difference

My xformer problems got solved while I was fixing another thing: stable-cascade-one-click-installer
