With the example below I get the following error:

Error executing tool. Co-worker mentioned not found, it must to be one of the following options:
- pilot

from crewai import Agent, Task, Crew

from langchain_community.llms import Ollama

import os

os.environ["OPENAI_API_KEY"] = "NA"


llm = Ollama(model="llama3")


# Agents
luke = Agent(
    role="pilot",
    goal="Destroy the Death Star",
    backstory="The young destined-to-be-Jedi pilot, summoned to attack the Death Star.",
    llm=llm,
)

leia = Agent(
    role="strategist",
    goal="Coordinate the attack on the Death Star",
    backstory="The Rebel leader, essential for strategy and communication.",
    llm=llm,
)

# Tasks
coordinate_attack = Task(
    description="""Leia must coordinate the mission,
    maintaining communication and providing strategic support.
    Leia must ensure that everything is in order, providing a safe path for Luke""",
    expected_output="""Successfully coordinated attack, Death Star destroyed. All units informed and aligned.""",
    agent=leia,
    allow_delegation=True,
)


destroy_death_star = Task(
    description="""Luke must pilot his X-Wing and shoot at the Death Star's weak point to destroy it.""",
    expected_output="""Death Star destroyed, mission successful.""",
    agent=luke,
)


# Crews
rebel_alliance = Crew(
    agents=[leia, luke],
    tasks=[coordinate_attack, destroy_death_star],
    verbose=2,
)


rebel_alliance.kickoff()

There are multiple issues with your code.

  1. manager llm only works with proccess.hierarchical
  2. it is generally recommended to use English for promoting and then just instruct to "translate" the response
  3. When using Ollama use the ollama model class not OpenAI from langchain_community.llms import Ollama

If i havn't missed anything, the coworker not being found is either because points 1-3 or because llama3 is "too dumb"

Actually this might be related to #602

3. When using Ollama use the ollama model class not OpenAI `from langchain_community.llms import Ollama `

I've updated the code in the description with what you indicated.

For the point 3, I used ChatOpenAI just like the example in the doc https://docs.crewai.com/how-to/LLM-Connections/#ollama-integration-ex-for-using-llama-2-locally, though.

Either way, the error still occurs.

This might be a problem in how the ollama or langchain outputs the steps for the agents.

But I did a bisect and found out crewAI was able to cope with that before 0b78106.
It was only after this commit this error started.

Without logs it's hard to figure out the reason. I've had the same problem when LLM (Mistral 0.3 in my case) return action input key as co-worker instead of required coworker and this caused the same misleading error about absent agent. I fix it in this PR. Already tested in my fork - it works fine. Maybe you can try this fix and see the result....
