torch.log(input, out=None) → Tensor
Returns a new tensor with the natural logarithm of the elements of input.
Parameters
- input (Tensor) – the input tensor.
- out (Tensor, optional) – the output tensor.
Example:
代码语言：javascript复制>>> a = torch.randn(5)
>>> a
tensor([-0.7168, -0.5471, -0.8933, -1.4428, -0.1190])
>>> torch.log(a)
tensor([ nan, nan, nan, nan, nan])
