AttributeError: 'RandomOverSampler' object has no attribute 'fit_sample'

I am trying to use RandomOverSampler from imblearn but I'm getting error.

Looking at other posts, there seems to be a problem with older versions, but I checked my versions and I have:

sklearn.__version__
'0.24.1'

imblearn.__version__
'0.8.0'

This is the code I'm trying to run:

from imblearn.over_sampling import RandomOverSampler

OS = RandomOverSampler(sampling_strategy='auto', random_state=0)
osx, osy = OS.fit_sample(X, y)

And the error I get is:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

      3 OS = RandomOverSampler(sampling_strategy='auto', random_state=0)
----> 4 osx, osy = OS.fit_sample(X, y)

AttributeError: 'RandomOverSampler' object has no attribute 'fit_sample'
Solution

  • You want OS.fit_resample(X, y), not fit_sample.
