Pycharm fails at transfer learning tutorial

1

Sorry if this is off topic!
Tryng to run the transfer learning tutorial
https://pytorch.org/tutorials/beginner/transfer_learning_tutorial.html
on Windows 10.
It works like a charm in the Anaconda command shell, but fails in Pycharm.
It crashes at the statement

Get a batch of training data

inputs, classes = next(iter(dataloaders[‘train’]))

The error message suggests a problem with forking and mentions freeze_support, but this seems unlikely.

Has anyone been able to run this tutorial in Pycharm?

All the best

More specifically, it’s iter(dataloaders[‘train’]) that fails.
The Dataloader object looks reasonable in the debugger.
I’ve tried adding
multiprocessing.freeze_support()
prior to the statement, to no effect.

Since the code works in the Anaconda CMD Prompt, it’s basically a Pycharm problem, right?

Solved.
Apparently, the problem did have to do with forking, and the solution was to put the code (not just the iter part) in a
if name == ‘main’:
block.
