❓ Questions and Help

When I run this command:

python scripts/data_collector/yahoo/collector.py download_data
--source_dir ~/.qlib/stock_data/source/us_data_2023
--start 2023-01-01
--end 2024-01-01
--interval 1d
--region US
--symbols MSFT,NVDA,TSLA

I get this error:

My LLM suggests there is a bug in the QLib script.

Am I missing any setting?

Hi, @AliMoeen
Thanks for your interest in qlib, I see your problem.

1. I think the program is correctly pointing to the US stock data.
2. the traceback you provided shows that there is an error in getting the list of stocks, we are actively working on this issue, you can pull PR 1975 to fix this issue temporarily.
3. There is no need to provide the symbol parameter when downloading the data. The documentation is here.
