class mindspore.ops.Reshape[source]

Reshapes the input tensor with the same values based on a given shape tuple.

The ‘input_shape’ can only have one -1 at most, in which case it’s inferred from the remaining dimensions and the number of elements in the input.

  • input_x (Tensor) - The shape of tensor is \((x_1, x_2, ..., x_R)\).

  • input_shape (tuple[int]) - The input tuple is constructed by multiple integers, i.e., \((y_1, y_2, ..., y_S)\). Only constant value is allowed.


Tensor, the shape of tensor is \((y_1, y_2, ..., y_S)\).


ValueError – Given a shape tuple, if it has several -1; or if the product of its elements is less than or equal to 0 or cannot be divided by the product of the input tensor shape; or if it does not match the input’s array size.

>>> reshape = ops.Reshape()
>>> output = reshape(input_x, (3, 2))
>>> print(output)
