Optim torch
WebJun 21, 2024 · This is because network.parameters() is on the CPU, and optim has based on those parameters. When you do network.to(torch.device('cuda')) the location of the parameters change, and are the same as the ones that optim was instantiated with. If you do re-instantiate optim, the optimizer will work correctly.
