Why I get this error when I use smote_variants? about smote_variants HOT 9 OPEN

Could you share the dimensions of X_trainTF and y_train?

Interesting, which version of Python and numpy are you using? There might have been some changes in the latest versions which have not been checked yet. (up to P3.9 were the tests executed, I should cover the most recent versions soon)

python version is 3.7.13
numpy version is 1.21.6

Cool, this is not the case then, it should work with this setup. If it is not much of a burden, could you please prepare a minimal working example, like replacing the X_trainTF and y_train with some random arrays of the same size, feed them into the MulticlassOversampling and see if it fails? I could use that as a minimal working example for debugging.

Also, could you please share the label distribution in y_train? Are the labels of integer type?

this is my google colab workspace https://colab.research.google.com/drive/1ETmdFjWEJdayBq_Ji3Eu6qKprrc0lC_G?usp=sharing

and the dataset file:

Perfect, I look into it!

Hi @ppleumyy, so, all the smote_variants tools operate on numerical arrays. Your y_train contains strings, and it is a pandas Series, while your X_trainTF is a sparse array (it needs to be dense). So with the following changes, everything seems to work as expected:

y_train[y_train == 'Level 1'] = 1
y_train[y_train == 'Level 2'] = 2
y_train[y_train == 'Level 3'] = 3
y_train[y_train == 'Level 4'] = 4
y_train[y_train == 'Level 5'] = 5
y_train[y_train == 'Other'] = 0

y_train= y_train.values

X_trainTF= X_trainTF.todense()
