-    def add_argparse_args(cls, parent_parser: ArgumentParser) -> ArgumentParser:
-        """Extend existing argparse by default `Trainer` attributes."""
-        parser = ArgumentParser(parents=[parent_parser], add_help=False)
+    def _get_argparse_args_and_types(cls) -> Generator[Tuple[str, Any, Any], None, None]:


Suggested change

def _get_argparse_args_and_types(cls) -> Generator[Tuple[str, Any, Any], None, None]:

def _get_init_arguments_and_types(cls) -> Generator[Tuple[str, Any, Any], None, None]:

sounds a bit better as it can be used elsewhere not only for argparser

Maybe in this case it’s worth to make this method public?

And also move the allowed_types to the method's input arguments?

yes, both are good suggestions, lest doing it...

I decided to make this method more general. Let's a client decides what arguments he needs. For instance, add_argparse_args is a "client" of this method, and it restricts the allowed types by itself.
What are your thoughts on this?

that would be nice, just thinking if is better to defien wanted args/types or ignored ones

joeddav · 2020-03-20T15:04:09Z

This PR works great for me with the exception of boolean casting. I.e. if I run with --checkpoint_callback 0 or false or anything but an empty value, then args.checkpoint_callback -> True, since bool('false') -> True.

This can be resolved with distutils:

bool('false')
# True
bool(distutils.util.strtobool('false'))
# False

Would it be possible to add a line to check for bool types and cast them using the above? Otherwise the behavior is quite counterintuitive.

Borda · 2020-03-20T15:18:11Z

good point, @joeddav could you do it in review mode as a suggestion (so it is clear and @alexeykarnachev can simply accept it) or follow-up PR?
