mindspore.numpy.empty_like(prototype, dtype=None, shape=None)[source]

Returns a new array with the same shape and type as a given array.


Input array must have the same size across a dimension. If prototype is not a Tensor, dtype is float32 by default if not provided.

  • prototype (Union[Tensor, list, tuple]) – The shape and data-type of prototype define these same attributes of the returned array.

  • dtype (mindspore.dtype, optional) – Overrides the data type of the result.

  • shape (int or sequence of ints, optional) – Overrides the shape of the result.


Tensor, array of uninitialized (arbitrary) data with the same shape and type as prototype.


ValueError – if prototype is not a Tensor, list or tuple.
