Python Argparse of Google Vision AI Product Search : I am trying to build a Google Vision AI product search system. I am using python.
I have uploaded a product set already.

However, when I would like to search the product set with python argparse using below python code, I got an error.
https://github.com/GoogleCloudPlatform/python-docs-samples/blob/master/vision/cloud-client/product_search/product_in_product_set_management.py

The case was when I typed :
python productsetmanagement.py --project_id="test-as-vision-api-v1" --location="asia-east1" list_product_sets 

I could find my product_set : set01

However, when I typed :
python productsetmanagement.py --project_id="test-as-vision-api-v1" --location="asia-east1" --product_set_id="set01" get_product_set

I got an error: the following arguments are required: product_set_id
I have already typed the product set id, may I know why I still got the error ? Did I use argparse wrongly?

Many thanks.
