oneflow.log

oneflow.log()

Returns a new tensor with the natural logarithm of the elements of input.

\[y_{i} = \log_{e} (x_{i})\]

Parameters

input (Tensor) – the input tensor.

For example:

>>> import oneflow as flow
>>> import numpy as np
>>> arr = np.random.randn(2, 3, 4, 5)
>>> input = flow.tensor(arr, dtype=flow.float32)
>>> output = flow.log(input)
