asc2.log

asc2.log(input: LocalTensor) → LocalTensor

Computes the element-wise natural logarithm of input.

The supported data types for the input are: float16, float32.

Parameters:

input – The input value (tensor)

Returns:

The result tensor

Return type:

LocalTensor

Raises:

RuntimeError – If the input dtype is not supported for this operation

Examples

Compute the element-wise natural logarithm of all tensor elements:

input = asc2.copy_in(tensor, [0, 0], [128, 256])
result = asc2.log(input)

This function can also be called as a member function on LocalTensor, as input.log(...) instead of log(input, ...).
