Hello,
I have a really simple questions but I did not manage to find any answer on the web …
I would like to extend torch.autograd. Lets assume that the forward function takes as imput a 2 * N vector of control points and generate an output (for instance deformed image).
What exactly should exactly be the output of the backward function ?
Should it be a single variable containing all the color map derivatives and if such what is the correct format to use ?
I thank you very much for your help.
