'MSELoss' object has no attribute 'next_functions' (original) (raw)

I am reading tutorial of learning pytorch, but I get stuck in one error as follow.

https://github.com/pytorch/tutorials/blob/master/beginner_source/blitz/neural_networks_tutorial.py

Lines from 184 to 186 are my source code. And I have replace grad_fn to creator as grad_fn throws error out.

Paste my error info below.

Traceback (most recent call last):
  File "./network.py", line 56, in <module>
    print(loss.creator.next_functions[0][0])
AttributeError: 'MSELoss' object has no attribute 'next_functions'
