ImportError: cannot import name 'safe_indexing' from 'sklearn.utils'

Whenever I try to run the following line of code:

from imblearn.under_sampling import NearMiss

for under-sampling (or over-sampling) imbalanced data on Jupyter notebook, I get this error:

ImportError Traceback (most recent call last)

Edit ..\Anaconda3\Lib\site-packages\sklearn\utils\ __init__.py.

Copy def _safe_indexing ... till next def and paste the code with renaming to def safe_indexing... .

Keep previous _safe_indexing as it is.

It solved the issue in this way.

In ~\Anaconda3\Lib\site-packages\yellowbrick\classifier\threshold.py module replace:

from sklearn.utils import indexable, safe_indexing

with

from sklearn.utils import indexable, _safe_indexing

After that, restart the kernel.

For imblearn.under_sampling, did you try reinstalling the package?:

pip install imbalanced-learn

conda:

conda install -c conda-forge imbalanced-learn

in jupyter notebook:

import sys
!{sys.executable} -m pip install <package_name>

If you have scikitlearn>=0.24 (as far as i see there is a dependency for imblearn now,as scikit-learn (>=0.23) https://imbalanced-learn.org/stable/install.html) you may want to try:

try:
    from sklearn.utils import safe_indexing
except ImportError:
    from sklearn.utils import _safe_indexing
