🐛 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:
