Try closing and restarting ipython. imblearn requires scikit-learn >= 0.20 and sometimes the runtime loads in an older version of scikit-learn.

If the issue still persists, then reinstall all packages together to make sure they are compatible.

  • $\begingroup$ I was getting a different import error with SMOTE and this worked for that as well. $\endgroup$ – TrentWoodbury Apr 6 at 12:27

You can use:

conda install -c conda-forge imbalanced-learn

to reinstall it. This solved my problem.

pip install Tensorflow


pip install imblearn 

After the installation restart the system, as The imblearn.tensorflow provides utilities to deal with imbalanced dataset in tensorflow, and imblearn uses Tensorflow as backend.
