The example on https://www.crewai.com/open-source does not work. To be clear, the error is just a pydantic error meaning the example is likely out of date and just needs to be updated.
I am not asking how to make this example work, just pointing out that the example provided is broken.
python 3.12.4
crew 0.67.1
Combine this into a single example
fromcrewaiimportAgent, Task, Crew, Process# Agent definitionresearcher=Agent(
role='Senior Researcher',
goal='Uncover groundbreaking technologies in AI',
backstory='Driven by curiosity, you explore and share the latest innovations.'
)
# Task definitionresearch_task=Task(
description='Identify the next big trend in AI with pros and cons.',
expected_output='A 3-paragraph report on emerging AI technologies.'
)
defmain():
print("forming crew")
# Forming the crew and kicking off the processcrew=Crew(
agents=[researcher],
tasks=[research_task],
process=Process.sequential
)
print("running crew")
result=crew.kickoff(inputs={'topic': 'AI in healthcare'})
print(result)
if__name__=="__main__":

and you get an error
