The community member is using the GraphRAG Notebook and fine-tuned models (Llama3.1 8b bnb 4bit for LM and Snowflake/snowflake-arctic-embed-l-v2.0 for embed model) to graph a book, but is seeing only nodes and no relationships. Another community member suggests that the issue could be due to the fine-tuning, but the original poster notes that even default OpenAI models are giving the same visualization. There is no explicitly marked answer in the comments.
