Is more a clarification question more then technical.
I need extract two class from my features extractors (CNN).
For doing that i have used
Where: dataLoad are my CNN output prediction and ids a zero tensor of the
same length of output class.
Now, I need to backward those independent outputs with a two different targets and different loss function as well.
Then, I have converted the specific sequence output (from gather) in autograd Variable and i set the flag “requires_grad=True”.
==> The question is: This it’s correct or i have lost the gradient of CNN?
I am sorry for the question.
