operators.py

r"""This file provides a location for operators that help exporting
models via onnx. E.g. shape_as_tensor and reshape_from_tensor_shape
are to make all dynamic sizes operations traceble.

NOTE: at one point these functions were implemented differently.
Since then we have implemented these directly in ATen, so this
file is kept purely for backward-compatibility.
