# 修改成自己的文件夹 注意文件夹最后要加上/
txt_to_xml("E:/train/side-detection/darknet-test/obj/txt/", "E:/train/side-detection/darknet-test/obj/pic/", "E:/train/side-detection/darknet-test/obj/xml/")修改：1.开头的对应字典，改成自己的类
2.最后放三个地址，txt，jpg，xml（自己新建）
注意：这个xml中没有difficult标签，所以可能会报错，报错看另一篇。
或者自己加一下，我对着我用labelImg标记生成的xml文件修改了一下（还有一点点不同，但是不影响）
