I briefly look through code noticed explicit reference to OpenAI eg

kotaemon/libs/ktem/ktem/index/file/graph/pipelines.py

Line 232 in 8be8a4a

, it might not be ready for local llms

Another issue is that graphrag is a separate program with own configuration. Which could be configured to other llm but it's a separate question microsoft/graphrag#657

@mkhludnev thanks. I can build the graphRAG and run the pipeline successfully with my local ollama after a investigation about graphrag component.

But I got error which point to the mismatch of embedding between openai and ollama during the query stage. This error is hidden in the kotaemon pipeline, seems a lot of work to fix it.

if someone can run ollama for graphrag. Please share the steps to us :）

Finally, it works. I will make a PR to this repo
