加载youtub视频的例子，原样复制代码本地执行，第二个提问之后就报错了 about langchain-chinese-getting-started-guide HOT 3 CLOSED

且初始化问答链需要更新这个，qa_prompt 替换为 condense_question_prompt

qa = ConversationalRetrievalChain.from_llm(ChatOpenAI(temperature=0.1,max_tokens=2048),retriever,condense_question_prompt=prompt)

不然报错

应该是这个类后续被修改了，我周末抽空改下这块的案例

我觉得是模板写错了，把模板改成

system_template = """
Use the following context to answer the user's question.
If you don't know the answer, say you don't, don't try to make it up. And answer in Chinese.
-----------
{question}
-----------
{chat_history}
"""

即把 {context} 改成 {question}，就可以了。
