mindspore.ops.csr_exp

mindspore.ops.csr_exp(x: CSRTensor)[source]

Returns csr_exponential of a CSRTensor element-wise.

\[out_i = e^{x_i}\]

Parameters: x (CSRTensor) – The input CSRTensor.
Returns: CSRTensor, has the same shape and dtype as the x.
Raises: TypeError – If x is not a CSRTensor.

Supported Platforms:: Ascend GPU CPU

Examples

>>> from mindspore import dtype as mstype
>>> from mindspore import Tensor, ops, CSRTensor
>>> 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_exp(x)
>>> print(output.values)
