[BUG] chatchat kb -r初始化知识库失败

[wukl001]

chatchat kb -r初始化知识库失败，报错内容说没开启ollama的11434的端口。我进入model_settings.yaml中删除除了xinfernece的一切配置，再次初始化，报错更离谱了。

Hello @wukl001! I'm here to help you solve bugs, answer questions, and assist you in becoming a contributor. I'm a bot designed to support you while you wait for a human maintainer. Let’s tackle your issue together!

I found some similar discussions that might be relevant to your issue:

1. 基于README_dev.md搭建环境，在初始化返回502错误的问题 - This discussion is about initialization errors, which might provide insights into your problem ^[1].

2. 启动langchain-chatchat的时候，加载模型阶段出现问题，请大神们帮忙看看问题出在哪里？ - This discussion involves issues during the model loading phase, which could be related to your configuration changes ^[2].

Regarding your specific issue, the error message "IndexError: list index out of range" suggests that the list available_llms is empty when trying to access its first element. This could be due to incorrect or missing configurations in your model_settings.yaml file. Ensure that the file is correctly configured with at least one language model specified under LLM_MODEL_CONFIG and MODEL_PLATFORMS. You might need to verify that the models are correctly set up and available for use ^[3].

Additionally, the connection error with the Xinference server indicates a possible misconfiguration in the server URL. Double-check the URL format and ensure that the server is running and accessible at the specified address.
