4 months ago The error you're encountering, ValueError: Could not parse dynamic plan, indicates an issue with the format or content of the dynamic plan string used in the ChainOfTableQueryEngine. To resolve this:
-
Ensure Correct Format: The dynamic plan should follow a specific format, with operations and arguments properly defined. It typically involves operation names followed by arguments, separated by specific delimiters.
-
Check Operation Names: Verify that the operation names in your dynamic plan match those expected by the parser. Any discrepancy in operation names can lead to parsing errors.
-
Dynamic Plan Completeness: Confirm that your dynamic plan string concludes with an
<END>marker to signify the end of the plan. -
Compatibility Check: The version of the llama_index library you're using might not fully support Python 3.11. Consider using a Python version that is known to be compatible with llama_index version 0.10.33, or check if there's an updated version of the library that supports Python 3.11.
If after these checks the issue persists, it might be beneficial to consult the library's documentation for examples of valid dynamic plans or reach out to the library's support community for further assistance.
