AttributeError: 'RCTree' object has no attribute 'codisp_with_cut_dimension'

Hi.

I'm following the example to obtain feature importance here, and even copying and running the code there as is, I get the following error:

AttributeError: 'RCTree' object has no attribute 'codisp_with_cut_dimension'

referring to the line:

   for tree in forest:
       for leaf in tree.leaves:
-->        codisp,cutdim = tree.codisp_with_cut_dimension(leaf)

Any ideia why might that be?

Thank you,

Hello, I could replicate the problem. It seems that you have installed rrcf by means of PyPi, pip install rrcf which installs rrcf v.0.4.4. However, that version of the package was uploaded on Apr 30, 2023 whereas the code implementing codisp_with_cut_dimension (PR #100) was merged into master afterwards on May 22, 2023 (see commit history). The solution therefore is to install from source by running pip install rrcf/. I have tested it and it seems to resolve the issue.

I use mamba virtual env, but I can't running pip install rrcf/. It shows error ERROR: Invalid requirement: 'rrcf/': Expected end or semicolon (after name and no valid version specifier) rrcf/. How could I solve this problem? Thank you.
