[BUG] Agents getting stuck in loop since move to LiteLLM #1355

Closed chappers00 closed 1 month ago

chappers00 commented 1 month ago

Description

After updating to CrewAI 0.63.6 and changing the agent to the new LiteLLM style configuration tasks which were taking around 15-20 seconds are now sometimes not completing, and when they are completing it is taking up to 10 calls to the LLM before it can decide on calling a tool.

We use Anthropic Claude 3.5 Sonnet via AWS Bedrock

The agent was previously able to complete tasks with just a few LLM calls, and now it seems to get stuck in a loop repeatedly calling the LLM.

Running with Debug logging shows this body of text in the completion request sent by LiteLLM:

{"text": "I did it wrong. Tried to both perform Action and give a Final Answer at the same time, I must do one or the other"}

Steps to Reproduce

Create a single agent crew with a single task where there are tools attached to the task. (See Screenshots/Code snippets for full steps to reproduce)

Expected behavior

The agent should use a tool that it has access to in order to complete the task within a reasonable number of calls to the LLM

Screenshots/Code snippets

import os from crewai import Agent, Crew, Task from crewai import LLM from langchain_community.agent_toolkits import FileManagementToolkit

MODEL_ID = "bedrock/anthropic.claude-3-5-sonnet-20240620-v1:0"

DIRECTORY = "."

os.environ["AWS_REGION_NAME"] = "us-east-1" os.environ["AWS_DEFAULT_REGION"] = "us-east-1"

agent_llm = LLM(model=MODEL_ID)

tools = FileManagementToolkit( root_dir=str(DIRECTORY), selected_tools=["read_file", "write_file", "list_directory"] ).get_tools()

agent = Agent( role="Example Agent Role", goal= "Example Agent goal", backstory="Example agent backstory", memory=True, verbose=True, allow_delegation=True, llm=agent_llm )

task = Task( description = ( "Get any available information to help the Developer understand " "the business context of the application under test" ), expected_output = "A concise summary provided to the Developer " "of the any relevant documentation including READMEs.", tools=tools, agent= agent )

crew = Crew( agents=[agent], tasks=[task], memory=True, embedder={ "provider": "aws_bedrock", "config":{ "model": 'amazon.titan-embed-text-v2:0', "deployment_name": 'ec_embeddings_titan_v2' } } )

Possible Solution

It seems the prompt being used with LiteLLM is not giving a valid response from the LLM

Found the bug, pushing a fix

joaomdmoura commented 1 month ago

I have not been able to test against sonnet yet, but I was able to replicate this with another LLM. Version 0.64.0 is out and fixes this :) Let me know if it is a problem still and we can re open but I got it to pass with the LLM I was having issues with

chappers00 commented 1 month ago

Thanks @joaomdmoura I can confirm it's working now with Bedrock + Anthropic on 0.64.0, appreciate the swift fix
