Pytorch error attribute error: ‘tensor’ object has no attribute ‘backword’ According to the error description, there is no backword attribute. error code loss.backword() # Reverse Propagation correct loss.backward() # Reverse Propagation I mistyped a a letter. There is no error prompt on the Jupiter notebook editor, which is difficult to find

24.07.2020 · But this returns error: “distance_loss” object has no attribute ‘backward’. It is my understanding that backward method is automatically implemented in nn.module. What goes wrong here? Also do I somehow need to append the learnable parameters of distance_loss() to model.parameters() for optimizer to know?

torch.Tensor.backward¶ Tensor. backward (gradient = None, retain_graph = None, create_graph = False, inputs = None) [source] ¶ Computes the gradient of current tensor w.r.t. graph leaves. The graph is differentiated using the chain rule. If the tensor is non-scalar (i.e. its data has more than one element) and requires gradient, the function additionally requires specifying gradient.
