如何将pandas dataframe导出为二进制格式的文件并让c++读取？

import pandas as pd

# 创建一个示例dataframe
data = {'Name': ['John', 'Emma', 'Mike'],
        'Age': [25, 28, 30],
        'City': ['New York', 'London', 'Paris']}
df = pd.DataFrame(data)

# 将dataframe保存为pickle格式的文件
df.to_pickle('dataframe.pkl')

#include <iostream>
#include <fstream>
#include <boost/archive/binary_iarchive.hpp>
#include <boost/serialization/vector.hpp>

int main() {
    std::ifstream file("dataframe.pkl", std::ios::binary);

    // 使用boost库进行反序列化
    boost::archive::binary_iarchive ia(file);
    std::vector<std::string> column_names;
    std::vector<int> ages;
    std::vector<std::string> cities;

    // 反序列化dataframe的列名
    ia >> column_names;

    // 反序列化dataframe的Age列
    ia >> ages;

    // 反序列化dataframe的City列
    ia >> cities;

    // 打印读取的数据
    for (int i = 0; i < column_names.size(); i++) {
        std::cout << column_names[i] << ": " << ages[i] << ", " << cities[i] << std::endl;
    }

    file.close();
    return 0;
}
