Error 401 - Unauthorized - Docker Building process

Hi guys,

I was running the docker building process when I received the message below:

[1/9] FROM nvcr.io/nvidia/pytorch:21.06-py3@sha256:74a31ca4b89914fa0c23238514ec40d2322406826c7b9d99a437ed8c512da6e1:


failed to copy: httpReadSeeker: failed open: failed to authorize: rpc error: code = Unknown desc = failed to fetch anonymous token: unexpected status: 401 Unauthorized

Has anyone had a similar problem that could help me?

Thanks in advance.
