BUG: ImportError: cannot import name 'FakeQuantizeBase' from 'torch.quantization'

See original GitHub issue

After your recent release, I got this error from my code. I can only use my code by downgrading fvcore version to previous one.

I guess that the problem is related to the last commit where torch.quantization is imported if the torch version is smaller than 1.11. However, that does not maintain the past behavior since the references to torch.quantization were replaced assuming that the import works (and before it was verified that the torch version is larger than 1.8).
