如何将numpy数组发送到armadillo (C++)并从armadillo返回numpy数组

import numpy as np

arr = np.array([[1, 2, 3], [4, 5, 6]])

import numpy as np
import armadillo as arma

arr = np.array([[1, 2, 3], [4, 5, 6]])
mat = arma.mat(arr.tolist())

#include <armadillo>

int main() {
    arma::mat mat;
    // 接收armadillo矩阵的代码逻辑
    return 0;
}

#include <armadillo>
#include <numpy/arrayobject.h>

int main() {
    arma::mat mat;
    // 处理armadillo矩阵的代码逻辑

    // 将armadillo矩阵转换为numpy数组
    npy_intp dims[2] = {mat.n_rows, mat.n_cols};
    PyObject* np_array = PyArray_SimpleNewFromData(2, dims, NPY_DOUBLE, mat.memptr());

    // 返回numpy数组给Python
    return 0;
}

import ctypes
import numpy as np

# 加载C++编译后的动态链接库
lib = ctypes.CDLL("your_library.so")

# 调用C++代码并获取返回的numpy数组
get_numpy_array = lib.get_numpy_array
get_numpy_array.restype = ctypes.py_object
result = get_numpy_array()

# 打印返回的numpy数组
print(result)
