mindspore.Tensor.cosh

Tensor.cosh() → Tensor

Computes hyperbolic cosine of self element-wise.

\[out_i = \cosh(self_i)\]
Returns

Tensor, has the same shape as self.

Raises

  • TypeError – If self is not a Tensor.

  • TypeError –

    • CPU/GPU: If dtype of self is not float16, float32 or float64, complex64, complex128.

    • Ascend: If dtype of self is not bool, int8, uint8, int16, int32, int64, float16, float32, float64, complex64, complex128 or bfloat16.

Supported Platforms:

Ascend GPU CPU
