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 traceable.
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.
