Is it a build WARNING or an actual error?

Asking as have not seen CI build failure due to this error before

[astroshim]

It's not actual error just error messsage.

[corneadoug]

It's not an ERROR and doesn't break the build.
It's more of a warning/info but when running it is shown with [ERROR] which can be misleading when looking for build errors.

I actually get a few more if I clean the repo like a new clone with: git clean -dxf
(Warning, this will wipe out your notebooks and config files)

However some of those errors are more related to deprecated versions and might need more tests if we update the dependencies.
Maybe it should be done in a different PR.
