PYTHON上数据储存：h5py

from：http://www.aichengxu.com/python/24309.htm

写入：

data = mp.array( [222,333,444] )

label = np.array( [0,1,0] )
img_num = np.array( [0,1,2] )
# 创建HDF5文件
file = h5py.File("TrainSet_rotate.h5","w")
# 写入
file.create_dataset("train_set_x", data = data)
file.create_dataset("train_set_y", data = label)
file.create_dataset("train_set_num",data = img_num)
# 。。。。。。。。。
file.close()

读取：

import numpy as np
import h5py
# 读方式打开文件
file=h5py.File("TrainSet_rotate.h5","r")
# 尽管后面有 "[:]", 但是矩阵怎么进去的就是怎么出来的，不会被拉长（matlab后遗症）
train_set_data = file["train_set_x"][:]
train_set_y = file["train_set_y"][:]
train_set_img_num = file["train_set_img_num"][:]
# .........
file.close()
