Detailed Image

This is the code below which shows the error.

from imblearn.under_sampling import NearMiss
nm = NearMiss()
X_res,y_res=nm.fit_sample(X,Y)

Answer 1

You are probably trying to under sample your imbalanced dataset. For this purpose, you can use RandomUnderSampler instead of NearMiss.

Try the following code:

from imblearn.under_sampling import RandomUnderSampler  

under_sampler = RandomUnderSampler()
X_res, y_res = under_sampler.fit_resample(X, y)

Now, your dataset is balanced. You can verify it using y_res.value_counts().

Cheers!
