I’ve installed pytorch 1.0 on windows.

When I try to use webcam demo provided by maskrcnn-benchmark 7. An error occured:
Traceback (most recent call last):
  File "webcam.py", line 80, in <module>
    main()
  File "webcam.py", line 64, in main

    if not torch.distributed.is_initialized():
AttributeError: module 'torch.distributed' has no attribute 'is_initialized'

But when I checked the pytorch 1.0 document, the torch.distributed module does have the is_initialized() method.
How to solve this problem
