mindspore.ops.coo_expm1
- mindspore.ops.coo_expm1(x: COOTensor)[source]
Returns exponential then minus 1 of a COOTensor element-wise.
\[out_i = e^{x_i} - 1\]- Parameters
x (COOTensor) – The input COOTensor with a dtype of float16 or float32.
- Returns
COOTensor, has the same shape as the x.

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