Too many attempt to download; and 'other_code_list' is not defined

Hello,

When trying to download the data for US model, there seem many attempt threads been started, while most of them are interrupted, guessing this is a issue from the website?

Also, after the first download is completed, it will run "for stock in tqdm(other_code_list):", but "other_code_list" seems not defined.

Any suggestion, thanks.
