AttributeError: module 'torch.distributed' has no attribute 'deprecated'

Hi!

I get this error on Windows 10 and torch=1.2.0 when just import apex

I think my system just not supports this, but it is not good behavior.

If you’ve already installed apex, remove it:

pip uninstall apex
rm -rf apex

Reinstall from @ptrblck 's fork of apex apex_no_distributed branch

git clone https://github.com/ptrblck/apex.git
cd apex
git checkout apex_no_distributed
pip install -v --no-cache-dir ./

Ah, got it. So, at that level, it’s a different issue. Now when I use your branch w/ PyTorch 1.2.0, removing all DDP, it works!
