Hi All,

Anyone able to get the marvin example working https://colab.research.google.com/github/run-llama/llama_index/blob/main/docs/examples/metadata_extraction/MarvinMetadataExtractorDemo.ipynb#scrollTo=rE2szbNgH056?

Plain Text

TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases

That error usually has to do with typing-extensions versions. Try pip install typing-extensions==4.5.0

although tbh I'm not sure if that marvin integration still works or not, it's very rarely used it seems 😅

Thanks Logan. Appreciate the response. What would your preferred approach be for generating Metadata?

Any other metadata extractor 🙂 lol

The pydantic metadata extractor is probably the most generic
