error: argument -s/--source is required

I copied this code from Github, but its not working to me.

Sample Code:

ap = argparse.ArgumentParser()
ap.add_argument("-s", "--source", required=True, help="Path to the source of shapes")
ap.add_argument("-t", "--target", required=True, help="Path to the target image")
args = vars(ap.parse_args())

and this output

usage: detect_leaf.py [-h] -s SOURCE -t TARGET
detect_leaf.py: error: argument -s/--source is required

please help me. thanks

Solution

  • The error message in your question title is pretty obvious.

    ap.add_argument("-s", "--source", required=True, help="Path to the source of shapes")

    You put required=True on this parameter. That means it's required. So, if you try to run this script, and don't put a --source (or -s) argument on the command line, you will get an error.

    If you don't want it to be required, don't put required=True.

    The output you show at the end of the question, on the other hand, cannot possibly come from this code. There is no -src or -trg parameter in your argparse spec. Maybe you're running a completely different program? If so, we can't debug that program by seeing the code to this one.
