torch.log2#

torch.log2(input:Tensor,*,out:Optional[Tensor])→Tensor#

Returns a new tensor with the logarithm to the base 2 of the elementsofinput.

$$y_i={\log }_2(x_i)$$yi​=log2​(xi​)

Parameters

input (Tensor) – the input tensor.

Keyword Arguments

out (Tensor,optional) – the output tensor.

Example:

>>>a=torch.rand(5)>>>atensor([ 0.8419,  0.8003,  0.9971,  0.5287,  0.0490])>>>torch.log2(a)tensor([-0.2483, -0.3213, -0.0042, -0.9196, -4.3504])
