Weighted Loss Possible Issue

[ArlindKadra]

I am noticing some very large fluctuations when working with weighted loss, in particular for task 233109.
Are we sure we are passing the weights correctly ? Using the weighted loss results to a drop in performance from 65.86 to 54.

Uncommenting the line of code below:

Auto-PyTorch/autoPyTorch/utils/implementations.py

Line 38 in ee685a9

classes, counts = classes[::-1], counts[::-1]

Yields 68.64 test set performance.
