Does Valohai support list parameters?

Valohai doesn't support list typed parameters. The currently supported parameter types are string, integer, float, and flag.

There is a workaround, where you'd use a string type parameter and define the list as comma-separated values.

- name: epoch_str
  type: string
  default: 4,5,6,7,8
  multiple-separator: ','
  multiple: separate

In your python script you can then parse the parameter with argparse:

import argparse

def parse_args():
    parser = argparse.ArgumentParser()
    parser.add_argument('--epoch_str', type=lambda arg: arg.split(','))
    return parser.parse_args()

args = parse_args()

for x in args.epoch_str:
    # Use the parameters

That will result in a list with strings. Note that you will need to convert the parameter values to for example integers or floats depending on your use case.
