Problems importing imblearn python package on ipyt

问题:

I installed https://github.com/glemaitre/imbalanced-learn on windows powershell using pip install, conda and github. But when I'm on iPython notebook and I tried to import the package using:

from unbalanced_dataset import UnderSampler, OverSampler, SMOTE

I get the error:

---

ImportError  Traceback (most recent call last) <ipython-input-9-ad6fd7440a05> in <module>()
----> 1 from imbalanced_learn import UnderSampler, OverSampler, SMOTE

ImportError: No module named imbalanced_learn

New to using windows for Python, do I have to install the package in some folder?

回答1:

If it don't work, maybe you need to install "imblearn" package.

Try to install:

• pip: pip install -U imbalanced-learn
• anaconda: conda install -c glemaitre imbalanced-learn

Then try to import library in your file:

• from imblearn.over_sampling import SMOTE

回答2:

Try this:

from imblearn import under_sampling, over_sampling

In order to import SMOTE:

from imblearn.over_sampling import SMOTE

Or datasets:

from imblearn.datasets import ...

回答3:

Type !pip install imblearn

in jupyter notebook. this worked for me.

回答4:

pip install -U imbalanced-learn should work, although make sure you've met the dependencies for numpy, scipy and scikit-learn.
