i am already check the six and joblib
these modules satisfied the requirement

[amueller]

This is not an error, it's a warning, and can be safely ignored.

[filipjakubowski]

It is not warning anymore.

Repos like scikit-learn depreciated six: https://github.com/scikit-learn/scikit-learn/pull/12916/files

[amueller]

True, it was removed in the last release. I'll fix it!

[filipjakubowski]

plot_interactive_tree.py

from sklearn.externals.six import StringIO
->
from io import StringIO

I made it work in my repo fork.

[amueller]

Pushed a fix here and to the notebook repo and to pipy. please let me know if it works.

[gcaldiera]

Similar error. Not sure if they are connected:

[amueller]

@gcaldiera thanks for reporting. I'm not sure why I didn't see that when I ran everything yesterday but it's definitely related. I'll look into it!

[amueller]

A work-around is changing the line to "from joblib import Memory"

[avulaankith]

I got this while installing

Thanks, can you try upgrading mglearn with pip and see if the error persists?

[gcaldiera]

No error now. Just a warning (see below) but it doesn't seem to be a problem. Thanks.

Thanks for reporting, not an issue for now, though :)
