random_selector
Overview
该技能通过 random_selector.py 执行 CSV 数据随机采样。
Instructions
1. 检查文件
确保 input_file 存在。
2. 构建命令
根据需求组合参数,仅提供用户明确指定的参数。若参数为可选(None),则不要在 shell 命令中包含该 flag。
3. 执行采样
使用以下模板执行:
python scripts/random_selector.py \
--input_file "{input_file}" \
--output_file "{output_file}" \
{ "--select_ratio " + str(select_ratio) if select_ratio else "" } \
{ "--select_num " + str(select_num) if select_num else "" } \
{ "--seed " + str(seed) if seed else "" }
