`deepaas-cli` returns exit code 1 even if the prediction is successful

[IgnacioHeredia]

This happens because, in the console script wrapper, sys.exit takes any non 0 returned value as exit code 1 (exception). (ref)

In cli.py:

def main():
    """Executes model's methods with corresponding parameters"""
    return None

--> exit code 0 (success)

def main():
    """Executes model's methods with corresponding parameters"""
    return 'success'

--> exit code 1 (error)

If we finally don't need them, consider removing returns from cli.py

@IgnacioHeredia Could you, please, elaborate more? What is the exact cli call and what line is suspicious? Because predict() supposes to return json response not "success". "return 0" is anyway the equivalent of "return success", any other number is error by definition, no?

Hi @vykozlov ,

I'm using the demo app, but I was replacing the whole main function with a mock response, just to test the exit code. So the exact cli call does not matter, because nothing was really being processed.

But anyway, if you want to see a real-life example, you can use the demo-app (in the no_file_args). The second command is printing the error code of the previous command.

The processing of demo app is successful and the output is what was expected, but the status code of deepaas-cli is 1. As I said in the first comment, I thought this could be somehow related to this.

Anyway, not a super big issue (for the moment), but worth keeping track (and fix if possible).
