xFormers Install Question

[alpergel]

Hi, I keep getting the warnings that XFormers is not installed, but whenever I try to install it with the suggested method on their github after Ive run the VGGsfm install script, I get breaking issues like: /anaconda/envs/vggsfm_tmp/lib/python3.10/site-packages/torchvision/io/image.py:13: UserWarning: Failed to load image Python extension: '/anaconda/envs/vggsfm_tmp/lib/python3.10/site-packages/torchvision/image.so: undefined symbol: _ZN3c1017RegisterOperatorsD1Ev'If you don't plan on using image functionality from torchvision.io, you can ignore this warning. Otherwise, there might be something wrong with your environment. Did you have libjpeg or libpng installed before building torchvision from source?
warn(

and significant cuda issues if I let it continue.

Is there any way xformers install could be integrated directly into the setup script?

Hey you can just ignore the warning of xformers not installed. xformers is not necessary for our usage.

@jytime would xformers speed it up?
