+PaddleOCR 也提供了数据格式转换脚本,可以将官网 label 转换支持的数据格式。 数据转换工具在 `train_data/gen_label.py`, 这里以训练集为例:
+
+```
+# 将官网下载的标签文件转换为 train_icdar2015_label.txt 
+python gen_label.py --mode="det" --root_path="icdar_c4_train_imgs/"  \

+                    --output_label="train_icdar2015_label.txt"

 解压数据集和下载标注文件后,PaddleOCR/train_data/ 有两个文件夹和两个文件,分别是:
 ```
