项目OCR实验（下）之文本识别

ERROR:root:DataLoader reader thread raised an exception!

方法1.看到修改深度，代码中没有深度的相关代码

import sys # 导入sys模块
sys.setrecursionlimit(3000) # 将默认的递归深度修改为3000

方法2.修改过cal_metric_during_train 设置为 False，还是会报错，请问如何解决？

该问题已经解决，数据集格式的问题。按照飞桨中数据集标签格式，不报错

你好，我用飞桨工具导出的识别数据集也是出现这个问题，请问一些你说的标签格式问题，是\t和分隔符 \n的原因吗

我的自己生成的数据可以被百度官方的标注工具，然后用标注工具导出后，报错跟你差不多。但又不太一样。

你好，我用飞桨工具导出的识别数据集也是出现这个问题，请问一些你说的标签格式问题，是\t和分隔符 \n的原因吗

您好，我是fork项目的时候没有注意作者的数据集提示：默认请将图片路径和图片标签用\t分割，如用其他方式分割将造成训练报错，更换数据集就没报这个错了；你的这个错误致命的Python错误:无法从堆栈溢出恢复，相关回答有：The error you're getting indicates that you have a function called do which calls itself, probably in an infinite loop. When a function does that too many times (calls itself inside itself, which causes it to call itself inside itself inside itself...) you get what's called a "stack overflow"，您看一下代码里是否有函数在无限循环。
