Issue with LangChain Misclassifying gpt-3.5-turbo-instruct as Chat Model

题意：**LangChain 将 gpt-3.5-turbo-instruct 错误分类为聊天模型的问题**

问题背景：

OpenAI deprecated its text-davinci-003 completion model. I've updated the model to gpt-3.5-turbo-instruct. I am encountering an issue with the LangChain where it incorrectly classifies the gpt-3.5-turbo-instruct model as a chat model. This is causing initialization problems in my code.

**OpenAI 已废弃其 text-davinci-003 完成模型。我已将模型更新为 gpt-3.5-turbo-instruct。在使用 LangChain 时，我遇到了一个问题，它错误地将 gpt-3.5-turbo-instruct 模型分类为聊天模型。这导致了代码中的初始化问题。**

Environment:

python = "^3.10"
langchain = "^0.0.130"
