When the execution starts locally the args are like:

Namespace(subparser='train', project='test', epochs=0)

then remotely they get converted to:

Namespace(subparser="['train', '--project', 'test', '--epoch', '0']", project='test', epochs=0)

Which is similar to what Tim reported a few messages above.

So when in the code I do something like if args.subparser == "train": ... I get a normal behaviour locally (i.e. True ), but not remotely because args.subarser is actually that weird string.
I solved it by chaing the condition to if "train" in args.subparser , which works in both situation, but it’s not very safe 🙂
