在Ubuntu20.04上配置OpenCV4时遇到编译错误，提示找不到Python.h。通过`locatePython.h`命令找到了多个Python头文件的位置，选择了/usr/include/python3.10/Python.h，并更新了CPATH和LD_LIBRARY_PATH环境变量来解决问题。

ubuntu20.04配置opencv4时出现报错：

fatal error: Python.h: No such file or directory
   17 | #include <Python.h>
      |          ^~~~~~~~~~
compilation terminated.

解决方案

找到Python.h位置

locate Python.h

结果：
