Why does docker pull fail with "unauthorized: authentication required" error?

Question

Docker

Hello.
trying to download Jupyter Notebook. Specifically, this "jupyter/datascience-notebook".
It downloads about 80%, and then disappears with an error

/usr/bin/docker-current: unauthorized: authentication required.

What does he need?
In the logs like this:

msg="Download failed: unauthorized: authentication required"
msg="Error trying v2 registry: unauthorized: authentication required"
msg="Attempting next endpoint for pull after error: unauthorized: authentication required"
