https://blog.csdn.net/google19890102/article/details/45672305 python read file-python reads and saves mat file
In the actual problem, the .mat file is a cell.
Read with scipy library
Through the scipy.io.loadmat method, the data read out is in dictionary format , which can be viewed through the function type(data).
import scipy.io #用于加载mat文件
import numpy as np
labels = scipy.io.loadmat('F:\\imagelabels.mat') #用scipy.io.loadmat读取.mat文件
print("labels:",labels)
#输出：labels: {'__header__': b'MATLAB 5.0 MAT-file, Platform: GLNX86, Created on: Thu Feb 19 15:43:33 2009',
#'__version__': '1.0', '__globals__': [], 'labels': array([[77, 77, 77, ..., 62, 62, 62]], dtype=uint8)}
data_labels=labels.get('labels') #取出字典里的labels
print("data_labels:",data_labels)
#输出：data_labels: [[77 77 77 ... 62 62 62]]
labels = labels['labels'][0] #取出字典里的labels id
print("labels:",labels)
#输出：labels: [77 77 77 ... 62 62 62]
