Pull request overview
This PR adds support for the aten::percentFormat operator in the PyTorch frontend. The implementation extracts the numeric value from a format string operation by returning the input tensor directly, since the OpenVINO IR cannot represent string formatting operations.
Changes:
- Added translation handler for
aten::percentFormatoperator that returns the input tensor - Registered the operator in the supported operations table
- Added test coverage with parametrized format strings

The format_str parameter is defined but never used in the test. The create_model method accepts format_str but hardcodes the format string on line 20. Either remove the parameter or update the model to use it.

The custom_eps value of 1e18 is extremely large and deserves a comment explaining why such a large epsilon is necessary for skipping result comparison.
| kwargs["custom_eps"] = 1e18 | |
| kwargs["custom_eps"] = 1e18 # Use an extremely large epsilon to effectively disable numeric result comparison. |

Inconsistent spacing in closing braces. Lines 21, 23, and 24 have trailing spaces while line 22 does not. Remove trailing spaces for consistency.

The logic for choosing between input(0) and input(1) based on input_size is not documented. Add a comment explaining why input(1) is returned when there are 2+ inputs and what these inputs represent.
