其实就是python怎么读取binnary file mnist的结构如下,选取train-images TRAINING SET IMAGE FILE (train-images-idx3-ubyte): [offset] [type] [value] [description] 0000 32 bit integer 0x00000803(2051) magic number 0004 32 bit integer...

dense_vector:稠密的浮点数向量。 sparse_binary_vector:稀疏的二值向量,即大部分值为0,但有值的地方必须为1。 sparse_float_vector:稀疏的向量,即大部分值为0,但有值的部分可以是任何浮点数。 integer:整型格式

例子如下: [python] view plain copy import scipy.io as sio import matplotlib.pyplot as plt import numpy as np # 创建4个变量,并赋予相应的取值 sio.savemat('testpython.mat', {'a': 1,'b': 2,'c': 3,'d': 4}) # 创建了一个变量x,并赋...
