unrecognized arguments: True

Code:

if __name__ == '__main__':
    parser = argparse.ArgumentParser(description='Build dataset')
    parser.add_argument('--do_plot', action="store_true",
                        help='Plot the images')
    args = parser.parse_args()

Error:

$ python make_dataset.py --do_plot True
usage: make_dataset.py [-h] [--do_plot]           
make_dataset.py: error: unrecognized arguments: True

Just one of reason (which I faced) and hope my hypothesis helps your problem is that on Ubuntu (on Windows, IDK but it's fine),

When you imported a function from a .py file (let say A.py) which having args (people create __main__ to test a feature function, let call A function ). The .py importing/using A could be confusedly parsing arguments because A.py also parse arguments and so on.

So, you could solve by refactoring, or just (temporarily) comment out them to run first.

You do not need to indicate True as far as I can tell, by just including --do_plot, it is telling it that you wanted to do plot. And plus, you did not configure it to take any arguments.

In the following line of the source code: 

if args.do_plot:

If you actually included --do_plot in the command lines, it will be evaluated as True, if not, it will be evaluated as False.

The problem is in the specification here:

parser.add_argument('--do_plot', action="store_true",
                    help='Plot ...')

You've declared do_plot as an option without an argument; the True afterward has no purpose in your argument protocol. This is an option that's off by omission, on when present.

As you've configured it, the --do_plot option does not take any arguments. A store_true argument in argparse indicates that the very presence of the option will automatically store True in the corresponding variable.

So, to prevent your problem, just stop passing True to --do_plot.
