.. sigmoid.rst: ####### Sigmoid ####### .. code-block:: cpp Sigmoid // Elementwise sigmoid operation Description =========== Produces a single output tensor of the same element type and shape as ``arg,`` where the value at each coordinate of ``output`` is the sigmoid of ``arg`` at the same coordinate.
