np.split()函数的作用是将一个数组拆分为多个子数组,跟Tensorflow中的slice()函数有点类似,但是np.split()函数返回的是多个数组,tf.slice()函数返回的则是被切取的一个张量,区别还是挺大的。 1.官方注释 官方的注释如下: """ Split an array into multiple sub-arrays. Parameters --- ary : ndarray Arra...
将一个array分成多个子array See also array_split Split an array into multiple sub-arrays of equal or near-equal size. Does not raise an exception if an equal division cannot be made. hsplit Split array into multiple sub-arrays horizontally (column-wise). vsplit Split array into multiple sub-...

2.]), array([ 3., 4.]), array([ 5., 6.])] In the above code numpy.array_split() function splits a one-dimensional numpy array a into multiple sub-arrays of equal or nearly-equal size. In this case, the array a is created using np.arange(7.0), which generates a sequence of...
您看到的行为只是与split松散相关。numpy数组后面有一个"矩形块"，它们不能引用多个独立的分配。（通过...
Example: Splitting an array into multiple sub-arrays using numpy.split()>>> import numpy as np >>> a = np.arange(8.0) >>> np.split(a, 2) [array([ 0., 1., 2., 3.]), array([ 4., 5., 6., 7.])] In the above code first, an array a of length 8 with values from ...
You could use numpy's array_split function e.g., np.array_split(np.array(data), 20) to split into 20 nearly equal size chunks. To make sure chunks are exactly equal in size use np.split. Share Improve this answer Follow answered Nov 20, 2016 at 4:32 Alex 12.8k77 gold badges69...

Split an array into multiple sub-arrays.Parameters: ary : ndarray Array to be divided into sub-arrays. indices_or_sections : int or 1-D array If indices_or_sections is an integer, N, the array will be divided into N equal arrays along axis. If such a split is not possible, an erro...
