tf.compat.v1.flags.ArgumentParser

Base class used to parse and convert arguments.

The :meth:parse method checks to make sure that the string argument is a legal value and convert it to a native type. If the value cannot be converted, it should throw a ValueError exception with a human readable explanation of why the value is illegal.

Subclasses should also define a syntactic_help string which may be presented to the user to describe the form of the legal values.

Argument parser classes must be stateless, since instances are cached and shared between flags. Initializer arguments are allowed, but all member variables must be derived from initializer arguments only.

Methods

flag_type

flag_type() -> Text

Returns a string representing the type of the flag.

parse

parse(
    argument: Text
) -> Optional[_T]

Parses the string argument and returns the native value.

By default it returns its argument unmodified.
