Fairseq: Issue with fb_pathmgr

[hufuss]

Hello,
I am running the interactive translation (via PyTorch Hub) example.

When I run the command
en2de = torch.hub.load('pytorch/fairseq', 'transformer.wmt16.en-de', tokenizer='moses', bpe='subword_nmt')

I am getting the following error:

File "torch/hub/pytorch_fairseq_master/fairseq/checkpoint_utils.py", line 140, in load_checkpoint_to_cpu
    from fairseq.fb_pathmgr import fb_pathmgr
ImportError: No module named 'fairseq.fb_pathmgr'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/lib/python3.5/site-packages/torch/hub.py", line 363, in load
    model = entry(*args, **kwargs)

  File "torch/hub/pytorch_fairseq_master/fairseq/checkpoint_utils.py", line 145, in load_checkpoint_to_cpu
    except (ModuleNotFoundError, ImportError):
NameError: name 'ModuleNotFoundError' is not defined

Can you please help me resolve this?

Thanks!
