Assume a have variables a
and b
, and c = f(a, b)
and d = g(a, b)
. I want to differentiate z = c+d
wrt a
and b
assuming (!) that d
is fixed and not propagating through it. Can I set requires_grad
of d
to zero or using d.data
instead of d
whenever I don’t want to propagate gradients? Or use d.detach()
somehow? Thanks!
if d is fixed, then why don’t differentiate c wrt a and b?
Ok, suppose you want to differentiate z = c * d wrt a and b. Yes, you could do z = c*d.detach(), then d will not be propogated through.
