HTTPError: HTTP Error 404: Not Found for torch.hub.load('pytorch/fairseq', 'transformer_lm.wmt20.en')

[AdaUchendu]

🐛 Bug

After downloading the appropriate packages, I run torch.hub.load('pytorch/fairseq', 'transformer_lm.wmt20.en') to download the model but I seem to always get the HTTP 404 Error. I have also successfully loaded this model in the past (early this year), however, without changing any of the code, I get the following error. Also, I use Google colab so I always download the lastest version of the repo.

To Reproduce

Steps to reproduce the behavior (always include the command you ran):

1. Run cmd '....'
2. See error
