tune does not run smoothly on Windows. This cleans up some blockers:
- use cross-platform shutils.get_terminal_size instead of Popen(stty)
- somehow Trainer.workers is None at the end of test_commands.py, so the cleanup command was erroring. The error was not fatal, but was printing in the logs.
- if run locally, the log files are all written to the same location, so the rync-based syncing solution is not needed. This is the real fix for issue #20747
In a [recent review](https://discuss.python.org/t/experience-with-python-3-11-in-fedora/12911) of the experience of the Fedora team porting packages to the upcoming python 3.11, they remarked that most of the work was in removing deprecated aliases in unittest. I came across a few of these when looking at unrelated test failures, the DeprecationWarnings caught my eye. So a made a quick sweep of the code, using `git grep` to find occurances of the deprecated aliases:
old | new
---|---
assertEquals | assertEqual
assertNotEquals | assertNotEqual
assertRaisesRegexp | assertRaisesRegex
These changes are needed for two reasons.
**`__grouping_doc_end__` is in the wrong place**
If you look at the part of the Ray documentation where the tag is referenced, you'll read
> You can use the MultiAgentEnv.with_agent_groups() method to define these groups:
However, if you look at the code snippet below, you'll see the implementation of `to_base_env` in addition to the implementation of `with_agent_groups`.
To remove `to_base_env` from the code snippet, we need to move `__grouping_doc__end__`.
**Black cannot format `multi_agent_env.py`**
For some reason, Black errors while formatting `multi_agent_env.py`. However, if we move `__grouping_doc_end__` up, the issue is resolved.

I've figure out that the test case `//rllib:tests/test_gpus::test_gpus_in_local_mode` failed due to deadlock in local mode.
In local mode, if the user code submits another task during the executing of current task, the `CoreWorker::actor_task_mutex_` may cause deadlock.
The solution is quite simple, release the lock before executing task in local mode.
In the commit 7c2f61c76c:
1. Release the lock in local mode to fix the bug. @scv119
2. `test_local_mode_deadlock` added to cover the case. @rkooo567
3. Left a trivial change in `rllib/tests/test_gpus.py` to make the `RAY_CI_RLLIB_DIRECTLY_AFFECTED ` to take effect.
