argv parsing in 5.x to pass a set, how to

Bắt đầu bằng cách tái hiện lệnh Voila được hiển thị và kiểm tra cách argparse xử lý TagRemovePreprocessor.remove_cell_tags. Xác định các tùy chọn có giá trị dạng tập hợp được phân tích như thế nào trong hành vi của 5.x, sau đó xác minh việc hoàn tất thành công khi lệnh chấp nhận tùy chọn mà không phát sinh TraitError; issue không đề cập đến tệp hoặc test nào trong repository.

After upgrading to 5.x I can no longer use the command I once was with voila - after having read through other issues and the docs I see the parsing has changed.
https://github.com/voila-dashboards/voila/issues/813

The difficulty I am running into - is I don't see how to pass a set as an option?

For example, I used to use:

voila --no-browser --ExecutePreprocessor.timeout=300 --theme=dark --TagRemovePreprocessor.remove_cell_tags='{"hide"}'

but I get the below error when opening notebooks with voila:

Jan 21 16:56:38 abc-123-086427 voila[2580]:   File "/home/ubuntu/miniconda3/envs/data_analysis_lab/lib/python3.8/site-packages/traitlets/traitlets.py", line 610, in _validate

Jan 21 16:56:38 abc-123-086427 voila[2580]: traitlets.traitlets.TraitError: The 'remove_cell_tags' trait of a TagRemovePreprocessor instance expected a set, not the str '{"hide"}'.

So for --TagRemovePreprocessor.remove_cell_tags the error is now saying it is expecting a set and not a str

I have tried many combinations such as:

voila --no-browser --ExecutePreprocessor.timeout=300 --theme=dark --TagRemovePreprocessor.remove_cell_tags=hide

Searching through cli options in argparse I don't see a way to pass a set from the cli that TagRemovePreprocessor.remove_cell_tags is expecting.
