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: """ Traceback (most recent call last): File "/Users/didi/miniconda3/envs/qlib/lib/python3.8/concurrent/futures/process.py", line 239, in _process_worker r = call_item.fn(*call_item.args, **call_item.kwargs) File "/Users/didi/miniconda3/envs/qlib/lib/python3.8/concurrent/futures/process.py", line 198, in _process_chunk return [fn(*args) for args in chunk] File "/Users/didi/miniconda3/envs/qlib/lib/python3.8/concurrent/futures/process.py", line 198, in return [fn(*args) for args in chunk] File "/Users/didi/Code/Github/qlib/scripts/dump_bin.py", line 264, in _dump_bin self._data_to_bin(df, calendar_list, features_dir) File "/Users/didi/Code/Github/qlib/scripts/dump_bin.py", line 238, in _data_to_bin np.hstack([date_index, _df[field]]).astype("<f").tofile(str(bin_path.resolve())) ValueError: could not convert string to float: 'SH600000' """

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