mindspore.numpy.hsplit

View Source On Gitee
mindspore.numpy.hsplit(x, indices_or_sections)[source]

Splits a tensor into multiple sub-tensors horizontally (column-wise). It is equivalent to split with axis=1 (default), the array is always split along the second axis regardless of the array dimension.

Parameters
  • x (Tensor) – A Tensor to be divided.

  • indices_or_sections (Union[int, tuple(int), list(int)]) – If integer, N, the tensor will be divided into N equal tensors along axis. If tuple(int), list(int) or of sorted integers, the entries indicate where along axis the array is split. For example, [2,3] would, for axis=0, result in three sub-tensors x[:2], x[2:3]. If an index exceeds the dimension of the array along axis, an empty sub-array is returned correspondingly.

Returns

A list of sub-tensors.

Raises

TypeError – If argument indices_or_sections is not integer.

Supported Platforms:

Ascend GPU CPU

Examples

>>> import mindspore.numpy as np
>>> input_x = np.arange(6).reshape((2, 3)).astype('float32')
>>> output = np.hsplit(input_x, 3)
>>> print(output)
(Tensor(shape=[2, 1], dtype=Float32,
value=[[ 0.00000000e+00],
       [ 3.00000000e+00]]),
Tensor(shape=[2, 1], dtype=Float32,
value=[[ 1.00000000e+00],
       [ 4.00000000e+00]]),
Tensor(shape=[2, 1], dtype=Float32,
value=[[ 2.00000000e+00],
       [ 5.00000000e+00]]))
