Я часто получаю эту ошибку в агенте langchain. Я выполняю операцию RAG и использую инструменты и агенты langchain. Для приложения я использую сервисы AWS, такие как Bedrock и Lambda.
Вот как я определил агенты:
from langchain.agents.initialize import initialize_agent
agent = initialize_agent(
tools=tools,
llm=llm,
agent="zero-shot-react-description",
verbose=True
)
но я получаю ошибку типа:
handle_parsing_errors=True` to the AgentExecutor. This is the error: Could not parse LLM output: ``

Также отметим, что эта ошибка возникает не каждый раз, а примерно 1/5 раза.
Мой LangSmith показывает:ValueError: An output parsing error occurred. In order to pass this error back to the agent and have it try again, pass `handle_parsing_errors=True` to the AgentExecutor. This is the error: Could not parse LLM output: ` I now know the final answer to the original input.question

STRoutputparser сгенерировал ответ, но агент не сработал.
Попробовал то, что сказал агент: handle_parsing_error = true
, но ничего не вышло.
Пытался найти решения в Интернете, но ничего не нашел.
Пытался просмотреть документацию langchain, но не нашел подходящего решения.
