colab : model = torch.hub.load('pytorch/fairseq', 'roberta.large') error

Question

I tried the code below.

import torch

model = torch.hub.load('pytorch/fairseq', 'roberta.large')

I got the error below.

I searched tutorial colab for RoBERTa already, however, it does not work either.

Does any one have save issue? or have any solution for this?
