WebThe “balanced” mode uses the values of y to automatically adjust weights inversely proportional to class frequencies in the input data: n_samples / (n_classes * np.bincount … WebI have no weights still it gets revoked when i run the code. I get this part the if no weight is provide each sample has same weight. Edit i have came to conclusion that sklearn bagging classifier has an issue. I think the "if support_sample_weight:" in the above code must not have else part and all the code in else must be below bootstrap.
