mindspore.ops.Size

class mindspore.ops.Size(*args, **kwargs)[source]

Returns the size of a tensor.

Returns an int scalar representing the elements size of input, the total number of elements in the tensor.

Inputs:

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

Outputs:

int, a scalar representing the elements size of input_x, tensor is the number of elements in a tensor, \(size=x_1*x_2*...x_R\).

Raises

TypeError – If input_x is not a Tensor.

Supported Platforms:

Ascend GPU CPU

Examples

>>> input_tensor = Tensor(np.array([[2, 2], [2, 2]]), mindspore.float32)
>>> size = ops.Size()
>>> output = size(input_tensor)
>>> print(output)
