I observed that syft is creating grad tensors for all tensors, even if freezed and calling backwards on them. The grad tensors are useful with unfreezed layers only, right? The lead was from the autograd[0] documentation. If I remove the grad_tensor creation for the freezed layers and leave it None, it seems to work fine. Any advices?
