How to fix: No samples will be generated with the provided ratio settings. (imblearn)

Question

I have this code:

from imblearn.over_sampling import ADASYN

Y = df.target
X = df.drop('target', axis=1)

ad = ADASYN()
X_adasyn, y_adasyn = ad.fit_sample(X, Y)

getting this error:

ValueError: No samples will be generated with the provided ratio 
settings.

Answer 1

Make it a two. There is github and it explicitly says:

if not np.sum(n_samples_generate):
                raise ValueError("No samples will be generated with the"
                                 " provided ratio settings.")

but, yeah......#
