mindspore.ops.coo_atanh

mindspore.ops.coo_atanh(x: COOTensor)[source]

Computes inverse hyperbolic tangent of the input element-wise.

\[out_i = \tanh^{-1}(x_{i})\]

Warning

This is an experimental API that is subject to change or deletion.

Parameters

x (COOTensor) – Input COOTensor. The data type should be one of the following types: float16, float32.

Returns

A COOTensor, has the same type as the input.

Raises

TypeError – If x is not a COOTensor.
TypeError – If dtype of x is not float16 or float32.

Supported Platforms:: Ascend GPU CPU

Examples

>>> from mindspore import dtype as mstype
>>> from mindspore import Tensor, ops, COOTensor
>>> indices = Tensor([[0, 1], [1, 2]], dtype=mstype.int64)
>>> values = Tensor([-1, 2], dtype=mstype.float32)
>>> shape = (3, 4)
>>> x = COOTensor(indices, values, shape)
>>> output = ops.coo_atanh(x)
>>> print(output.values)
