# PURPOSE: Create a function that retrieves the following 3 command line inputs
|
|
# from the user using the Argparse Python module. If the user fails to
|
|
# provide some or all of the 3 inputs, then the default values are
|
|
# used for the missing inputs. Command Line Arguments:
|
|
# 1. Image Folder as --dir with default value 'pet_images'
|
|
# 2. CNN Model Architecture as --arch with default value 'vgg'
|
|
# 3. Text File with Dog Names as --dogfile with default value 'dognames.txt'

# Imports python modules

|
# TODO 1: Define get_input_args function below please be certain to replace None
|
