Describe your problem

A large PDF was added into the RAGFlow cohort. It worked well until graph extraction. OCR and other analysis were working well. Knowledge graph extraction error:ERROR: [Errno 111] Connection refused was printed. Could anyone help?

Knowledge graph depends on LLM that's set in System model setting.

My problem is that no api key is provided, when i use ragflow to run Knowledge graph. The model used is deployed on my computer, so how can i do to solve

this issue. Thank you kind - hearted guys!

Set a chat model in System model setting before KG processing.

亲身体验成功：windows环境，早前安装好的ollama，开放防火墙[11434]端口，查看宿主机ip比如 192.168.1.103，进入 ragflow容器内尝试 telnet 192.168.1.103 11434，可以联通就不会再有问题
