mindspore.ops.ACos

class mindspore.ops.ACos

Computes arccosine of input tensors element-wise.

\[out_i = cos^{-1}(x_i)\]

Inputs:

• x (Tensor) - The shape of tensor is \((N,*)\) where \(*\) means, any number of additional dimensions. The data type should be one of the following types: float16, float32, float64.

Outputs:

Tensor, has the same shape and dtype as x.

Raises

• TypeError – If x is not a Tensor.

• TypeError – If dtype of x is not float16, float32 or float64.

Supported Platforms:

Ascend GPU CPU

Examples

>>> acos = ops.ACos()
>>> x = Tensor(np.array([0.74, 0.04, 0.30, 0.56]), mindspore.float32)
>>> output = acos(x)
>>> print(output)
