[xucailiang]

For Local Development (Optional - With Neo4j)

# Start Neo4j with GDS plugin
docker run -d --rm \
  --name neo4j \
  -p 7474:7474 -p 7687:7687 \
  -e NEO4J_AUTH=neo4j/password \
  -e "NEO4J_PLUGINS=[\"graph-data-science\"]" \
  neo4j:latest

Running Example(set DASHSCOPE_API_KEY first)

python examples/graph_rag/graph_knowledge_example.py

🚀 Running Tests

# Run tests with Neo4j
NEO4J_AVAILABLE=true pytest tests/graph_rag/ -v

# Run all tests (mock mode - works in GitHub Actions)
pytest tests/graph_rag/ -v

# Skip tests requiring Neo4j GDS plugin
pytest tests/graph_rag/ -v -m "not requires_gds"

📝 Note on GDS Community Detection Tests

Community detection tests require real API models and are not included in the test suite.

To test GDS features: Use examples/graph_rag/graph_knowledge_example.py with real DashScope API credentials.

Do we have any progress on this? I can provide more documentation to assist with the review if needed. Our team has been using a temporary repository for some time and would like to switch back to the main Agentscope repository for feature updates.
Thank you for your efforts. @qbc2016

Great suggestion, I've fixed these issues, here's the information on the fix. @qbc2016

Fix(graph_rag):

• reorganize graph RAG example and improve documentation
• Use relative import instead of absolute import.
• Move graph RAG example from examples/graph_rag/ to examples/functionality/graph_rag/
• Add comprehensive README.md with setup instructions, features, and usage guide
• Update Neo4j configuration documentation with Docker setup example
• Translate example script from Chinese to English for better accessibility
• Remove hardcoded API key requirement and use environment variable instead
• Improve error handling for missing DASHSCOPE_API_KEY
• Remove path manipulation code from example script for cleaner implementation
• Update documentation configuration to remove expected failing examples list
• Remove redundant qdrant-client dependency from pyproject.toml
• Refactor RAG module imports and documentation strings for consistency
• Enhance example with better user prompts and configuration information
