Description

Context

Context OpenVINO component responsible for support of PyTorch models is called as PyTorch Frontend (PT FE). PT FE converts a model represented as TorchScript model to a model in OpenVINO opset.

Add Support for the following operations:

aten::__contains__
aten::nan_to_num
aten::__is__
aten::__isnot__

What needs to be done?

What needs to be done? Implement conversion rule and/or transformation to support the new operation. Implement operation tests in tests/layer_tests/pytorch_tests. Please consider different data types, but keep reasonable number of test cases

Contributor guide

Research direction
Study existing conversion rules for similar PyTorch operations in the OpenVINO PyTorch Frontend. For each operation (aten:: contains , aten::nan to num, aten:: is , aten:: isnot ), identify the corresponding OpenVINO op or implement a transformation. Write tests in tests/layer tests/pytorch tests covering various data types.
