项目场景：
在使用百度 paddleOCR 的测试代码和百度自动标注工具 PPOCRLabel 时，出现报错：
OMP: Error #15: Initializing libiomp5md.dll, but found libiomp5md.dll already initialized.
OMP: Hint This means that multiple copies of the OpenMP runtime have been linked into the program.
PPOCRLabel ：输入PPOCRLabel --lang ch报错为：
OMP: Error #15: Initializing libiomp5md.dll, but found libiomp5md.dll already initialized.
OMP: Hint This means that multiple copies of the OpenMP runtime have been linked into the program. That is dangerous, since it can degrade performance or cause incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an unsafe, unsupported, undocumented workaround you can set the environment variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause crashes or silently produce incorrect results.

解决方案：
找到相关的xx.py, 用pycharm或其他工具打开，添加这两个语句：
import os
os.environ["KMP_DUPLICATE_LIB_OK"]="TRUE"
重新运行，问题解决。
