mindspore.ops.log2

mindspore.ops.log2(input)

Compute the logarithm to the base 2 of the input tensor element-wise.

\[y_i = \log_2(input_i)\]

Warning

If the input value of operator log2 is within the range (0, 0.01] or [0.95, 1.05], the output accuracy may be affected.

Parameters

input (Tensor) – The input tensor.

Returns

Tensor
