Process spawning error on Windows

[szgeri]

On windows, train_ae.py will display a process spawning related error, because on Windows, the subprocess will import the main module, and because of that, it'll also execute it.

Solution:

Put this line after the imports: if name == 'main':

and increase the indentation of the rest of the file.

I intentionally did not create a PR for this to not change the ownership of the whole code because of the required indentation.

Hello, thanks for reporting the issue, this code was only tested under linux, so not a surprise that things might need small adjustments for windows.

No worry about that, please go ahead for the PR ;)
