Ubuntu c++调用python脚本(Anaconda)

环境配置

1. 首先创建一个anaconda虚拟环境，环境名字可自己确定，这里使用 call 作为环境名：

$ conda create -n call python==3.8

2. 安装成功后激活call环境

$ source activate
$ conda activate call

编辑~./bashrc文件，设置使用deeplabv3+_cityscapes环境下的python3.8

alias python='~/anaconda3/envs/call/bin/python3.8'

4. 更新环境变量

$ source ~/.bashrc

5. 再次激活 call

conda activate call

代码准备

  SET(CMAKE_BUILD_TYPE Release)
ENDIF()

set(PYTHON_LIBRARIES "/home/mirrorubuntu/anaconda3/envs/call/lib/libpython3.8m.so")
add_executable(call call.cpp)
target_link_libraries(call ${PYTHON_LIBRARIES})

c++ call.cpp

 }
 pFunc = PyObject_GetAttrString(pModule, "main");
 PyEval_CallObject(pFunc, NULL);      //调用函数
 Py_Finalize();
 return 0;
}
