The DGL website suggests installing DGL with CUDA 11.3 support using the following command:
pip install dgl -f https://data.dgl.ai/wheels/cu113/repo.html
However, this does not work. The version installed does not have cuda compatbility. Furthermore, if you visit https://data.dgl.ai/wheels/cu113/repo.html you can see that this page is empty (there are no pip wheels).
