I need 2.11 because of an xformers version dependency requires at least 2.11 (I’ve tried xformers==0.0.35 and 0.0.33.post1 and get the message below; xformers 0.0.34 and 0.0.33 won’t install at all)
Here is the run-time error which suggests this 2.11:
WARNING[XFORMERS]: xFormers can't load C++/CUDA extensions. xFormers was built for:
PyTorch 2.11.0+cu130 with CUDA None (you have 2.8.0)

Please reinstall xformers (see https://github.com/facebookresearch/xformers#installing-xformers)
