you need to install xformers.
after installing CUDA and related pyTorch version (that matches with the CUDA version), xformers can be installed by:

git clone https://github.com/facebookresearch/xformers.git
cd xformers
git submodule update --init --recursive
pip install .

However, there might be some challenges and dependencies during the installation that needs to be mitigated. That took some time from me, but finally worked!
