How to set “task_args” in the artist erasing evaluation

[JianWang21]

I found:
parser.add_argument(
"--task_args",
nargs="*",
help="""Extra arguments for the task. Acceptable arguments:
task=general: concepts(list[str]), num_templates(optional, int, default=80), num_images_per_template(optional, int, default=10);
task=artwork: datasets(list[str]);
task=i2p: None.
task=coco: None.
""",

However, I am still unsure how to set "task_args". Could you show an example? Thx!
