phidata 및 Ollama를 사용하여 I 에이전트 구축-파이썬 튜토리얼-php.cn

Building I Agents with phidata and Ollama

이 기사에서는 phidata와 Ollama 로컬 LLM을 사용하여 웹 검색, 재무 분석, 추론 및 검색 증강 생성을 위한 AI 에이전트를 만드는 방법을 살펴보겠습니다. 코드는 llama3.2 모델을 사용합니다. 다른 모델을 사용하려면 사용하려는 모델을 다운로드하고 코드에서 model_id 변수를 바꿔야 합니다.

피다타(Phidata)란 무엇입니까?

에이전트 시스템을 구축, 제공, 모니터링하기 위한 오픈 소스 플랫폼입니다.

https://www.phidata.com/

올라마란 무엇인가요?

Ollama는 로컬 LLM(대형 언어 모델)의 배포 및 사용을 단순화하도록 설계된 플랫폼 및 도구 세트입니다.

https://ollama.ai/

이 글에서는 llama3.2 모델을 사용하겠습니다.

UV 란 무엇입니까?

Rust로 작성된 매우 빠른 Python 패키지 및 프로젝트 관리자입니다.
https://github.com/astral-sh/uv

uv를 사용하고 싶지 않다면 uv 대신 pip를 사용해도 됩니다. 그런 다음 uv add 대신 pip install을 사용해야 합니다.

이 글에서는 phidata와 Ollama를 이용해 5개의 AI 에이전트를 만들어 보겠습니다.
참고: 시작하기 전에 ollama Serve를 실행하여 ollama 서버가 실행 중인지 확인하세요.
