This thing uses pytorch, the bane of everything that attempts to make pypi installs sane. As a human, you need to read https://pytorch.org/get-started/locally/ https://pytorch.org/get-started/locally/ and install the correct version, depending on your pytorch-version/os/packaging-system/hardware-platform combo. It's bad. It's several conflicting index-urls messing with your requirements. It also doesn't work if you pick the wrong thing. Or we need something like a "setup.py" that is turing-complete, to dynamically pick up the correct dependency for you. `pip install -r requirements.txt` is not enough.
