Tensor Comparison API

[GregHattJr]

Description

Currently API reading of the Tensors is blocked by the inability to read tensor (.pt) files on a non-host machine. Once this issue is resolved we will have the ability to read the tensor files from a given report. The UI will allow users to check the tensors of a given operation against the golden tensor (if the comparison exists).

New API Endpoints

Tensor Comparison
api/compare-tensor/local/<tensor-id>
api/compare-tensor/global/<tensor-id>

These endpoints will check the global_tensor_comparison_records and local_tensor_comparison_records and return the diff if the comparison files exist.

Changes to Existing API

Operation Details

Each Input/Output will have a comparisons node with an optional local and global which are TensorComparisonRecords
