Exercise

Backpropagation using PyTorch

Here, you are going to use automatic differentiation of PyTorch in order to compute the derivatives of x, y and z from the previous exercise.

Instructions
100 XP
  • Initialize tensors x, y and z to values 4, -3 and 5.
  • Put the sum of tensors x and y in q, put the product of q and z in f.
  • Calculate the derivatives of the computational graph.
  • Print the gradients of the x, y and z tensors.
