Executing with a trailing \ in the arguments sets the variable new to the truthy value '\\' and deletes all progress

[jonas-klesen]

A rather frustrating issue:

calling it with a trailing \ like
lightweight_gan --data full_cleaned256/ --name c256 --models_dir models --results_dir results \

sets the variable new to the truthy value '\' and deletes all progress.

This might well be an issue with Fire but might be mitigated or fixed here too, I am unsure about that.

Thanks.
