torch.log#

torch.log(input,*,out=None)→Tensor#

Returns a new tensor with the natural logarithm of the elementsofinput.

$$y_i={\log }_e(x_i)$$yi​=loge​(xi​)

Parameters

input (Tensor) – the input tensor.

Keyword Arguments

out (Tensor,optional) – the output tensor.

Example:

>>>a=torch.rand(5)*5>>>atensor([4.7767, 4.3234, 1.2156, 0.2411, 4.5739])>>>torch.log(a)tensor([ 1.5637,  1.4640,  0.1952, -1.4226,  1.5204])
