Hi,
I am new to PyTorch, and I encountered a question.
There is not any change in training loss and validation loss after I changed the learning rate several times (as shown below). But if I change the batchsize, training loss and validation loss on each epoch changed.
I wanna know why the training loss and validation loss on each epoch did not change.
Thanks!
