pybind11的处理过程
我首先安装了pybind，参考了许多教程，但很多教程的貌似都来自微软导出pyd的方法，但是实际上linux下导出so文件而非pyd文件，后续运行的实例来自https://github.com/tdegeus/pybind11_examples（代码就不再本文中介绍了），因为python版本问题一直无法成功运行，所以我按照github的结构重新配置了文件（即下载pybind11源文件到当前目录，使用非安装方式，而无需再Cmakelists里进行任何修改），但仍然无法正常运行。后来看有说是python版本问题导致能够导出so却无法运行，所以后续就尝试了几种更改python版本的方式，运行成功。

版本问题
- 对于版本问题，首先尝试了再安装导出so文件对应的python版本10下执行，然后更改到python3.7也正常运行了
python3.10

python3.7
- 按照这种方法更改（设置python3.7对应的目录）bashrc没起作用
