numpy.dsplit()

numpy.dsplit(ary, indices_or_sections) [source]

Split array into multiple sub-arrays along the 3rd axis (depth).

Please refer to the split documentation. dsplit is equivalent to split with axis=2, the array is always split along the third axis provided the array dimension is greater than or equal to 3.

Examples

>>> x = np.arange(16.0).reshape(2, 2, 4)
>>> x
array([[[  0.,   1.,   2.,   3.],
        [  4.,   5.,   6.,   7.]],
       [[  8.,   9.,  10.,  11.],
        [ 12.,  13.,  14.,  15.]]])
>>> np.dsplit(x, 2)
[array([[[  0.,   1.],
        [  4.,   5.]],
       [[  8.,   9.],
        [ 12.,  13.]]]),
 array([[[  2.,   3.],
        [  6.,   7.]],
       [[ 10.,  11.],
        [ 14.,  15.]]])]
>>> np.dsplit(x, np.array([3, 6]))
[array([[[  0.,   1.,   2.],
        [  4.,   5.,   6.]],
       [[  8.,   9.,  10.],
        [ 12.,  13.,  14.]]]),
 array([[[  3.],
        [  7.]],
       [[ 11.],
        [ 15.]]]),
 array([], dtype=float64)]
