C++ 调用 Python 失败

我需要在C++中调用Python函数。
Python:

import tkinter as tk
class GUI:
  def __init__(self):
    self.root=tk.Tk()
  def run(self):
    self.root.mainloop()

C++:(此时Python以编译成pyd,名曰:main.pyd)

#include <iostream>
#pragma comment(lib,"python310.lib")
#pragma comment(lib,"python3.lib")
#pragma comment(dll,"python3.dll")
#pragma comment(dll,"python310.dll")
#pragma comment(zip,"base_library.zip")
#pragma comment(pyd,"main.pyd")
using namespace std;
int main()
{
    GUI a;
    a.run()
}

但是它报错了:

未命名1.cpp: In function 'int main()':
未命名1.cpp:11:2: error: 'GUI' was not declared in this scope
GUI a;
^
未命名1.cpp:12:2: error: 'a' was not declared in this scope
a.run()
^
编译结果:


  • 错误: 2
  • 警告: 0
  • 输出文件名: 未命名1.exe
  • 输出大小:
  • 编译时间: 0.14s

我不知道应该怎么做。
我希望调用成功,大家能帮帮我吗?
