功能概述

该算子用于加载 TSV(Tab-Separated Values)格式的文件并格式化为统一的数据集格式,输出为 JSONL 格式。

核心参数

参数类型必填默认值说明
input_pathstring是-输入TSV文件路径或目录
output_pathstring是-输出JSONL文件路径
text_keyslist否['text']文本字段名列表
add_suffixbool否False是否添加文件后缀信息
num_procint否1并行处理的进程数

输入数据格式

输入可以是:

  1. 单个 TSV 文件:/path/to/data.tsv
  2. TSV 文件目录:/path/to/tsv_directory/

输出数据格式

输出为 JSONL 格式,每行一个样本。

使用示例

命令行调用

# 加载单个TSV文件
python scripts/run_tsv_formatter.py \
  --input_path /path/to/input.tsv \
  --output_path /path/to/output.jsonl

# 指定文本字段
python scripts/run_tsv_formatter.py \
  --input_path /path/to/input.tsv \
  --output_path /path/to/output.jsonl \
  --text_keys text

# 加载目录中的所有TSV文件
python scripts/run_tsv_formatter.py \
  --input_path /path/to/tsv_directory \
  --output_path /path/to/output.jsonl \
  --add_suffix

参数说明

  • --input_path: 输入TSV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(默认 ['text'])
  • --add_suffix: 是否添加文件后缀信息
  • --num_proc: 并行进程数,默认1

注意事项

  1. TSV 使用 Tab (\t) 作为分隔符
  2. 输入文件必须是有效的 TSV 格式
  3. 空值或None的文本样本会被自动过滤
