• 为这个问题添加了一个非常描述性的标题。
• 使用集成搜索在LangChain文档中进行搜索。
• 使用GitHub搜索查找类似的问题，但没有找到。
• 我确信这是LangChain中的一个bug,而不是我的代码。
• 通过更新到LangChain的最新稳定版本(或特定集成包)无法解决此bug。

示例代码

代码如下：

from langchain.chat_models import AzureChatOpenAI
from config import *

chat_model = AzureChatOpenAI(
        openai_api_type=OPENAI_API_TYPE,
        openai_api_version=OPENAI_API_VERSION,  
        openai_api_key=OPENAI_API_KEY,
        azure_deployment=AZURE_DEPLOYMENT,
        openai_api_base=OPENAI_API_BASE
    )

messages = [
    (
        "system",
        "You are a helpful assistant that translates English to French. Translate the user sentence.",
    ),
    ("human", "I love programming."),
]
chat_model.invoke(messages)
