Hi Ptrbclk
Sorry I have aquestion , I passed the balanced data 4000 positive and 4000 negative as DatasetTrain to the random split train_len for 70 % and valid_len for 30 %
TrainData1, ValidationData1 = random_split(DatasetTrain,[train_len, valid_len])

After that TrainData1 and ValidationData1 can be unbalanced?
I think since it is randomly they can be unbalanced.
