[royerloic]

The error you encountered appears to be related to a metaclass conflict in the EventedModel class. This is a common issue in Python when a class inherits from multiple classes with incompatible metaclasses.

Here’s a step-by-step approach to resolving this issue:

1. Check Dependencies: The problem might arise from incompatible versions of pydantic (which is often used in the EventedModel class) or other dependencies. Ensure that the versions of the installed packages are compatible. You can check the installed versions using:

   pip list

Please post that list here.

2. Check napari Version: Ensure that the version of napari you are using is compatible with napari-chatgpt. You might want to try installing an earlier or the latest version of napari to see if the problem persists:

   pip install napari==0.5.2

3. Reinstall the Environment: If the above steps do not work, consider creating a new clean virtual environment and reinstalling napari and napari-chatgpt to ensure that no conflicting packages are present.

Also, please post more information about your system which will help us resolve this...
