ValueError: could not convert string to float: 'SH600000' when i use dump_bin.py

🐛 Bug Description

To Reproduce

Steps to reproduce the behavior:

1. python scripts/data_collector/baostock_5min/collector.py download_data --source_dir ~/.qlib/stock_data/source/hs300_5min_original --start 2022-01-01 --end 2022-01-30 --interval 5min --region HS300

2. python scripts/dump_bin.py dump_all --csv_path ~/.qlib/stock_data/source/hs300_5min_original --qlib_dir ~/.qlib/qlib_data/samples

Error:

The above exception was the direct cause of the following exception:

Additional Notes

Start with scripts/dump_bin.py, especially _data_to_bin and the dump_all path, then inspect the CSV output produced by scripts/data_collector/baostock_5min/collector.py. Confirm why the SH600000 value reaches numeric conversion and identify the expected input schema. Done means the documented reproduction completes without the ValueError and produces the requested Qlib data.
