So I am trying to multiply my loss by a value: self.strength, but this strength value doesn’t seem to have the desired effect. For example, if self.strength is equal to 1000, the output with my optimizer, is almost the same as having self.strength be equal to 2000, 5000, 15000, etc…
self.loss = self.crit(input, self.target) * self.strength

And then I use .backward()
self.loss.backward(retain_graph=True)

The other variables I am using are:
self.crit = nn.MSELoss()
self.target = input.detach()

My strength value should result in significantly different results between values like 2000, 5000, and 15000.
This seemed to work in Lua/Torch, so I am at a loss here as to why it’s not working in PyTorch.
