mindspore.numpy.append(arr, values, axis=None)[source]

Appends values to the end of a tensor.

  • arr (Tensor) – Values are appended to a copy of this tensor.

  • values (Tensor) – These values are appended to a copy of arr. It must be of the correct shape (the same shape as arr, excluding axis). If axis is not specified, values can be any shape and will be flattened before use.

  • axis (None, int, optional) – The axis along which values are appended. If axis is not given, both arr and values are flattened before use, default is None.


Tensor, a copy of tensor with values appended to axis.

  • TypeError – If input arguments have types not specified above.

  • ValueError – If specified axis exceeds arr.ndim.
