The code to calculate calculate grad of f wrt y has a missing import

import torch
import torch.autograd # missing.
x = torch.tensor(3.)
y = torch.tensor(2., requires_grad=True)
z = torch.tensor(5.)
f = 4 * x**3 + 3 * y**2 + 2*z
print(grad(f, y))

Thanks a lot for the note. I just updated it and added the missing from torch.autograd import grad
