make_parquet_list 没能正确产生spk2parquet_xxxx.json

[MrXsc]

Describe the bug
I'll examine the file to understand the context and find where spk_list should be defined.

    with open(spk2parquet_file, 'w') as f:
        json.dump({k: parquet_file for k in list(set(spk_list))}, f, ensure_ascii=False, indent=2)
    logging.info('spend time {}'.format(time.time() - start_time))

To Reproduce
run make_parquet_list.py

Expected behavior
all spk2parquet_xxxx.json file will be empty.
