AG2 0.5 upgrade breaks `from autogen import ...` — how to fix?

Question

After upgrading the ag2 Python package from 0.41 to 0.5 with pip install ag2 --upgrade, imports such as from autogen import SwarmResult, AssistantAgent, SwarmAgent and from autogen.coding import DockerCommandLineCodeExecutor started failing. What caused the breakage and how do I restore the imports?

Status: fixed. The issue was closed as completed after the reporter ran a maintainer-suggested uninstall/reinstall that restored the imports.

Maintainer @marklysze suggested running:

```bash
pip uninstall openai pyautogen ag2
pip install ag2
```

The issue author confirmed this worked and that they no longer had import issues. They were upgrading from AG2 0.41 and were not sure whether pyautogen was also installed; the thread does not identify the exact cause of the broken imports.

As an alternative, one commenter reported that using the `pyautogen` package instead of `ag2` also works. The maintainers also asked for the full traceback and which package manager was being used, but the uninstall/reinstall was reported as sufficient. As general advice, if imports still fail after a clean reinstall, check whether any other installed package provides an `autogen` top-level module.

Ran `pip uninstall openai pyautogen ag2` followed by `pip install ag2` as suggested by maintainer @marklysze. The reporter confirmed the import issues were gone.
