使用示例
命令行调用
# 加载单个CSV文件
python scripts/run_csv_formatter.py \
--input_path /path/to/input.csv \
--output_path /path/to/output.jsonl
# 指定文本字段
python scripts/run_csv_formatter.py \
--input_path /path/to/input.csv \
--output_path /path/to/output.jsonl \
--text_keys text \
--text_keys title
# 加载目录中的所有CSV文件
python scripts/run_csv_formatter.py \
--input_path /path/to/csv_directory \
--output_path /path/to/output.jsonl \
--add_suffix
# 指定编码格式(如GBK)
python scripts/run_csv_formatter.py \
--input_path /path/to/input.csv \
--output_path /path/to/output.jsonl \
--encoding gbk
参数说明
--input_path: 输入CSV文件或目录路径--output_path: 输出JSONL文件路径--text_keys: 文本字段名,可重复指定多个--add_suffix: 是否添加文件后缀信息--num_proc: 并行进程数,默认1--encoding: CSV文件编码格式,默认utf-8,如GBK文件可指定 --encoding gbk
注意事项
- 输入文件必须是有效的 CSV 格式
