I’m trying to train a model using GPUs from a cluster, and I haven’t been able to install the xformers package at all. I can’t figure out what’s going on. For reference, it’s running Anaconda 22.9.0 and Python 3.11.5.

I’ve tried:

conda install xformers::xformers
conda install xformers/label/dev::xformers
conda install xformers
conda install -c xformers xformers
conda install -c conda-forge xformers
conda install conda-forge::xformers
conda install -c xformers/label/dev xformers

All of which give me a PackagesNotFoundError. I’ve also tried

pip install xformers
pip install -U xformers --index-url https://download.pytorch.org/whl/cu118
pip install -U xformers --index-url https://download.pytorch.org/whl/cu121
pip install --pre -U xformers
pip install -v -U git+https://github.com/facebookresearch/xformers.git@main#egg=xformers

All of which give me a “error: metadata-generation-failed” error. It’s not an issue with pip or with conda (or at least not an obvious one) because I can download any other package fine.
