pip install pytorch-lightning["extra"] doesn't install FairScale

[mees]

🐛 Bug

The documentation [0] states that to enable sharded training one needs to install the extras packages with pip install pytorch-lightning["extra"], in my case only following the second option pip install https://github.com/PyTorchLightning/fairscale/archive/pl_1.1.0.zip actually installed fairscale.

To Reproduce

pip install pytorch-lightning["extra"]

Expected behavior

Fairscale gets installed.

Environment

I just checked this, FairScale is not getting installed through pip install pytorch-lightning["extra"]. I also had to do pip install https://github.com/PyTorchLightning/fairscale/archive/pl_1.1.0.zip.

My Environment

• PyTorch Version: 1.7.0
• OS: Linux
• How you installed PyTorch: pip
• Python version: 3.8.5

true, we skip all HTTP paths from packages...

there is some problem on PyPI side if they are passed to these dependencies...
eventually, we can install it with git+https://...
