가능한 원인:
이 오류는 google-cloud-aiplatform와 호환되지 않는 langchain-google-vertexai 버전을 사용하여 발생할 수 있습니다. langchain-google-vertexai 버전 1.0.2 이상이 필요합니다. 사용 중인 버전을 확인하려면 터미널에서 다음 명령어를 실행합니다.
pipshowlangchain-google-vertexai
추천 솔루션:
langchain-google-vertexai의 1.0.2 버전을 설치합니다. 이 버전에는 google-cloud-aiplatform 작업에 필요한 LangChain 도구 호출 업데이트가 포함되어 있습니다. langchain-google-vertexai 버전을 업데이트하려면 터미널에서 다음 명령어를 실행합니다.
pipinstalllangchain-google-vertexai--upgrade
업데이트 명령어를 실행한 후 터미널에서 다음 명령어를 실행하여 1.0.2 이상 버전을 사용 중인지 확인합니다.
