'MSELoss' object has no attribute 'next_functions'

[theodoruszq]

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'

This is related to PR #79. See my comment here.

tldr: changes in master pytorch.
creator -> grad_fn
previous_functions -> next_functions

[apaszke]

We shouldn't change tutorials (especially beginner ones) to work with master. They should always be prepared for the last release

[chsasank]

I agree. Previously pytorch docs used to be built with master rather than release. Following the same, PR #79 was merged. (When the PR was created, docs already had grad_fn and next_functions.)

In the future, we'll keep a branch for all compatibility breaking changes and merge it after the release.
