Hi guys,
Is more a clarification question more then technical.
I need extract two class from my features extractors (CNN).
For doing that i have used
dataLoad.data.gather(1, idsDim.view(-1,1)
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.
Best,
Nico
