log1p¶
- paddle.sparse. log1p ( x, name=None ) [source]
-
Calculate the natural log of (1+x), requiring x to be a SparseCooTensor or SparseCsrTensor.
\[out = ln(1+x)\]- Parameters
-
x (Tensor) – The input Sparse Tensor with data type float32, float64.
name (str, optional) – Name for the operation (optional, default is None). For more information, please refer to Name.
- Returns
-
A Sparse Tensor with the same data type and shape as
x
.
Examples
import paddle dense_x = paddle.to_tensor([-2, 0, 1], dtype='float32') sparse_x = dense_x.to_sparse_coo(1) out = paddle.sparse.log1p(sparse_x)
