Steps to reproduce

An error is reported when the knowledge base is used. The error information is as follows: worker-1 | File "/app/api/core/rag/datasource/vdb/vector_factory.py", line 135, in get_vector_factory worker-1 | from core.rag.datasource.vdb.opensearch.opensearch_vector import OpenSearchVectorFactory worker-1 | File "/app/api/core/rag/datasource/vdb/opensearch/opensearch_vector.py", line 6, in worker-1 | from opensearchpy import OpenSearch, Urllib3AWSV4SignerAuth, Urllib3HttpConnection, helpers worker-1 | File "/app/api/.venv/lib/python3.12/site-packages/opensearchpy/init.py", line 45, in worker-1 | from .client import OpenSearch worker-1 | File "/app/api/.venv/lib/python3.12/site-packages/opensearchpy/client/init.py", line 40, in worker-1 | from ..transport import Transport, TransportError worker-1 | File "/app/api/.venv/lib/python3.12/site-packages/opensearchpy/transport.py", line 32, in worker-1 | from opensearchpy.metrics import Metrics, MetricsNone worker-1 | File "/app/api/.venv/lib/python3.12/site-packages/opensearchpy/metrics/init.py", line 11, in worker-1 | from .metrics_events import MetricsEvents worker-1 | File "/app/api/.venv/lib/python3.12/site-packages/opensearchpy/metrics/metrics_events.py", line 13, in worker-1 | from events import Events worker-1 | ImportError: cannot import name 'Events' from 'events' (/app/api/events/init.py)

✔️ Expected Behavior

The knowledge base is running properly.

❌ Actual Behavior

The knowledge base cannot be used.

extent analysis

TL;DR

The most likely fix is to resolve the import error by checking the compatibility of the opensearchpy library with the current Python version.

Guidance

  • Verify that the opensearchpy library is compatible with Python 3.12, as the error occurs during the import of its modules.
  • Check the events module for any naming conflicts or incorrect imports that could cause the ImportError.
  • Review the opensearchpy documentation for any specific installation or configuration requirements for Python 3.12.
  • Consider testing the application with a previous version of Python to isolate the issue.

Notes

The error message suggests a compatibility issue between the opensearchpy library and Python 3.12. However, without more information about the library's version or the application's configuration, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: Check the compatibility of the opensearchpy library with Python 3.12 and consider downgrading to a compatible Python version if necessary.
