In an init script or a notebook, we can:

pip install --index-url=<our private pypi url> --extra-index-url=https://pypi.org/simple <a module>

In the cluster web UI (libraries -> install library), we can give only the url of our private repository, but no extra-index. That means that if our module gets dependencies to other modules available in pypi, it will fail, fetching them.

Is there a solution, using the web UI?
