Hinweise
In dieser Anleitung wird davon ausgegangen, dass Sie die Anleitung unter folgenden Links gelesen und befolgt haben:
Sie können das Verhalten des Agents auch über input hinaus anpassen, indem Sie zusätzliche Schlüsselwortargumente an query() übergeben.
response=agent.query(input={"input"=["What is Paul Graham's life in college?","How did Paul Graham's college experience shape his career?","How did Paul Graham's college experience shape his entrepreneurial mindset?",],},batch=True# run the pipeline in batch mode and pass a list of inputs.)print(response)
