@CCzzzzzzz Hello there! I'm here to help you with any bugs, questions, or contributions you may have while waiting for a human maintainer.

The error you're encountering is due to a circular import issue in the llama_index library. This is a known issue. To resolve this, you can try the following steps:

  1. Ensure you have the correct version of the neo4j package installed:

    pip install neo4j
  2. Check for circular imports: Sometimes, restructuring your import statements can help avoid circular import issues. Try importing Neo4jGraphStore at a different point in your code, or ensure that no other imports are causing a circular dependency.

  3. Use the correct import path: The import path for Neo4jGraphStore should be:

    from llama_index.graph_stores.neo4j import Neo4jGraphStore

If the issue persists, it might be related to a known circular import problem in the llama_index library. Unfortunately, there is no specific workaround for this issue mentioned in the provided context. You might need to wait for a fix from the maintainers or check for any updates in the library that address this issue [1].

For now, ensure that your environment is correctly set up and that you are using the latest versions of the required packages.

I think it's a mismatch between llama-index or other package versions.
