Build.py script fails: permissions error?

[bpickrel]

Can anyone help with a build error? I'm trying out Triton-server for the first time and tried to build it with the script:

./build.py -v --enable-all

Here's the error I got. Do I need an account or permissions that I don't know about? Am I running the right script?

ERROR: failed to solve: failed to copy: httpReadSeeker: failed open: failed to authorize: rpc error: code = Unknown desc = failed to fetch anonymous token: unexpected status from GET request to https://authn.nvidia.com/token?scope=repository%3Anvidia%2Ftritonserver%3Apull%2Cpush&service=registry: 401 Unauthorized

This script had to run for several hours before it failed, so it's not easy to just try running it again.

Could you please describe the environment in which you are trying to build the container?
