c++保存三维数组，保存为二进制文件，python 读取二进制文件/三维数组

动机：

实现c++和 python见得数据交换，数组数据交换。可以是三维图像数据

代码

int main()
{

	//1、定义一个三维数组
	float t[] = {1.0,1.0,2.0,2.0,3.0,3.0,11.0,11.0,22.0,22.0,33.0,33.0 };
	FILE *fp;
	fp = fopen("testRawt.raw", "wb");
	fwrite(t, sizeof(float), 12, fp);
	fclose(fp);
	std::cout << "aggregated predication image";

}

import os
import numpy as np

raw_path = r"d:\testRawt.raw"
raw_data = open(raw_path, 'rb').read()
raw_data_shape = (2, 3, 2)
np_raw_data = np.frombuffer(raw_data, dtype=np.float32)
reshaped_data = np_raw_data.reshape(raw_data_shape)

输出验证

读取顺序为常规顺序，先x方向, 再y方向，再尔z方向
