一、scio库

import scipy.io as scio

dataFile = 'G:/radar data/data(20,20).mat'
data = scio.loadmat(dataFile)

X_train = data['X_train']
Y_train = data['Y_train']

X_val = data['X_val']
Y_val = data['Y_val']

X_test = data['X_test']
Y_test = data['Y_test']

结果：

如果mat文件太大，存储时采用了下图第一个选项，采用scio读取就会报错

报错如下，此时就要采用第二种方法了

NotImplementedError: Please use HDF reader for matlab v7.3 files

二、h5py库

import h5py

data = h5py.File('G:/radar data/data(40, 40).mat','r')

X_train = data['X_train'][:]
Y_train = data['Y_train'][:]

X_val = data['X_val'][:]
Y_val = data['Y_val'][:]

X_test = data['X_test'][:]
Y_test = data['Y_test'][:]

结果：

注意：两种方法读取之后array的通道表示不一样，需要自行调整
