This makes it easy for us to convert a tensor to a numpy array. Summary. In this tutorial, you learned how to implement derivatives on various functions in PyTorch ... Webd~y dW: In this case, ~y varies along one coordinate while W varies along two coordinates. Thus, the entire derivative is most naturally contained in a three-dimensional array. We avoid the term \three-dimensional matrix" since it is not clear how matrix multiplication and other matrix operations are de ned on a three-dimensional array.
