It looks like we get pandas 2.0 on Google Colab, but according to docs Dataframe.map is new in 2.1

[embe-pw]

Manually installing newer pandas seems to work, but there is this warning:

google-colab 1.0.0 requires pandas==2.0.3, but you have pandas 2.2.2 which is incompatible.

It seems that this is already fixed in the repo, waiting for a release. cc @szymondudycz

Ok, the issue is fixed, waiting for the release. Meanwhile, we need to force pandas>=2.1 on Colab. Thank you!
