Grad_fn mmbackward
WebTensor and Function are interconnected and build up an acyclic graph, that encodes a complete history of computation. Each variable has a .grad_fn attribute that references a function that has created a function (except for Tensors created by the user - these have None as .grad_fn ).

WebJan 20, 2024 · How to apply linear transformation to the input data in PyTorch - We can apply a linear transformation to the input data using the torch.nn.Linear() module. It supports input data of type TensorFloat32. This is applied as a layer in the deep neural networks to perform linear transformation. The linear transform used −y = x * W ^ T + bHere x is the … WebNotice that the resulting Tensor has a grad_fn attribute. Also notice that it says that it's a Mmbackward function. We'll come back to what that means in a moment. Next let's continue building the computational graph by adding the matrix multiplication result to the third tensor created earlier:
