oneflow.log2

oneflow.log2(input)Tensor

Returns a new tensor with the natural logarithm to the base 2 of the elements of input.

\[y_{i} = \log2_{e} (x_{i})\]
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.log2(input)
