If you specified `nargs='*'` for `--sizes` you skip the commas on input and splitting. And `type=int` could make sure they are numbers. – hpaulj Feb 08 '18 at 22:09

Use argument parser from python : https://docs.python.org/3/library/argparse.html
You have examples in the doc.
Hint for your sizes: You can store it as a string and split it with ',' as a separator If sizes_string is "100,100,100", you do:
sizes = [int(s) for s in sizes_string.split(',')]

You can use an assert that will stop your program if the condition is not satisfied. `assert(layer == len(sizes))`. – Adrien Logut Feb 08 '18 at 20:27

Test the `len(sizes)` and complain to your user. `parse.errror` is convenient for issuing custom messages. – hpaulj Feb 08 '18 at 21:48
