Mnist label数据结构如上.
完整代码:
import struct
filename = ‘/home/xxxx/Downloads/train-labels.idx1-ubyte‘
binFile = open(filename, ‘rb‘)
buf = binFile.read()
index = 0
magic, train_label_num = struct.unpack_from(‘>II‘, buf, index)
print(magic)
print(train_label_num)
index += struct.calcsize(‘>II‘)
train_label_lis=[]
for i in range(train_label_num):
label_item = int(struct.unpack_from(‘>B‘, buf, index)[0])
train_label_lis.append(label_item)
index += struct.calcsize(‘B‘)
print(train_label_lis[0])
