Error when importing eli5

[leetabix]

When creating a virtual environment (using venv) and pip installing eli5 and jupyter lab, I'm unable to import eli5 as I receive the following error in my notebook:

ImportError: cannot import name 'if_delegate_has_method' from 'sklearn.utils.metaestimators' (\Lib\site-packages\sklearn\utils\metaestimators.py)

The issue appears to be due to scikit-learn depreciating the if_delegate_has_method decorator (in \Lib\site-packages\sklearn\utils\metaestimators.py) and replacing it with another decorator called available_if.

I've made the following updates to \Lib\site-packages\eli5\sklearn\permutation_importance.py and I'm now able to import the eli5 library:

• changed import statement to mention available_if instead of if_delegate_has_method
• replaced all mentions of:

    @if_delegate_has_method(delegate='wrapped_estimator_')

with

    @available_if(_estimator_has('wrapped_estimator_'))

• defined a new _estimator_has function for use with the above

Please let me know if you'd like me to propose the above update for merge.

Thanks,
James

@leetabix I think you should propose a pull request (PR) with the changes you've already made: it at least will be possible to install the working version of the package from your PR.

This commit addresses this as well:

@frosty24, is 840695d merged to the main branch of this repo? I'm a bit confused as GitHub informs:

[frosty24]

I picked this commit from the following open PR in this repo:
#31

Hi all! I ran into this error as well. I ended up installing scikit-learn==1.2.2 and then was able to import eli5 successfully.

[mprytoluk]

Is it possible for me to do something about this? I've stopped using eli5 in my project because I had to update scikit-learn.

[GegznaV]

If nobody answers, you may use SHAP values as an alternative: https://github.com/shap/shap That project is currently alive.

[RobertCarruthers-Ki]

Slight correction to the above.

Instead of replacing
@if_delegate_has_method(delegate='wrapped_estimator_')
with:
@available_if(_estimator_has('wrapped_estimator_'))
it should be replaced with the name of the function being checked for:
@available_if(_estimator_has('predict_proba')) (or whatever the relevant function is)
based on:
scikit-learn/scikit-learn#20506

This is implemented in my fork here

[DrJStrudwick]

Any update on this?

[mprytoluk]

I believe it's safe to say this project is dead. Some fork on this project would be great.
