mindspore.ops.csr_expm1
- mindspore.ops.csr_expm1(x: CSRTensor)[source]
Returns exponential then minus 1 of a CSRTensor element-wise.
\[out_i = e^{x_i} - 1\]- Parameters
x (CSRTensor) – The input CSRTensor with a dtype of float16 or float32.
- Returns
CSRTensor, has the same shape as the x.

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_expm1(x) >>> print(output.values) [-0.63212055 6.389056 ]
