We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Upgrade `release/1.4` to Torch 2.0.1 + TensorRT 8.6.1
- Also upgrade `main` to TensorRT 8.6.1 (as a commit to #1852)

--- END ISSUE ---

Below are some code segments, each from a relevant file. One or more of these files may contain bugs.
--- BEGIN FILES ---
Path: `py/versions.py`
Content:
