Printing torch properties fails on the Jetson Orin Agx

Platform:
* Jetson orin agx 32GB
* CUDA Version: 12.6
* PyTorch Version: 2.5.0a0+872d972e41.nv24.08

This line crashes the app (sam3_video_predictor.py:125)
```
logger.debug(
f"started new session {session_id}; {self._get_session_stats()}; "
f"{self._get_torch_and_gpu_properties()}"
)
```

With following error:
```
Error: Failed to start inference session: 'utf-8' codec can't decode byte 0x9e in position 116: invalid start byte
```

After removing the problematic code works as expected

Start in sam3_video_predictor.py around line 125 and trace _get_torch_and_gpu_properties() while reproducing the failure on the Jetson Orin AGX environment described. Confirm that starting an inference session no longer fails with the UTF-8 decoding error when the debug message is assembled, and verify the existing inference path still works.
