mindspore.ops.csr_atanh

mindspore.ops.csr_atanh(x: CSRTensor)[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 (CSRTensor) – Input CSRTensor. The shape is \((N, *)\) where \(*\) means, any number of additional dimensions. The data type should be one of the following types: float16, float32.

Returns

A CSRTensor, has the same type as the input.

Raises

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

Supported Platforms:: Ascend GPU CPU

Examples

>>> indptr = Tensor([0, 1, 2, 2], dtype=mstype.int32)
>>> indices = Tensor([3, 0], dtype=mstype.int32)
>>> values = Tensor([-1, 2], dtype=mstype.float32)
>>> shape = (3, 4)
>>> x = CSRTensor(indptr, indices, values, shape)
>>> output = ops.csr_atanh(x)
>>> print(output.values)
