Jupyter Notebook 설치해보기

 

 

 

보통은 파이썬을 공부할때 파이썬을 설치하고 파이참 등의 별도 개발툴을 설치해 사용했다.

주피터노트북은 일종의 파이썬 개발도구이다. 그런데 개발에 특화되었다기 보다는 학습에 특화된 개발도구이다.

웹 기반으로 개발환경으로 웹에서 코드를 입력하고 실행하면 그 결과를 출력해준다.

 

일단 설치하고 실행해보고 얘기하자.

 

설치는 편하게 pip install jupyter 하면 된다.

뭐 많이도 설치한다.

 

 

 

설치 후 구동은 아래와 같이 jupyter notebook 하면 된다.

위처럼 막 뭐라뭐라 뜨고 아마 웹페이지가 하나 열릴거다. 기본 포트가 8888이므로 localhost:8888로 접근하면 접근이 가능하다. 위 메세지 친절하게 써있듯이 토큰이 포함된 url을 입력해야 정상적으로 접근이 가능하다.

http://localhost:8888/?token=0439324741df4a68fe89520330e55d22c33f64540293c657

 

 

혹시 포트를 변경하고 싶으면 아래와 같이 옵션을 주면 된다.

우측 상단에 보면 New가 보일거다. 새로 하나 만들어서 테스트해보자.

 

 

 

 

아래와 같은 화면을 볼 수 있는데 아마 파이썬 관련 구글링할때 많이 접했을 수 있다.

 

 

 

이것 저것 입력하고 Run 해보면 아래처럼 오류도 출력해주고 결과도 출력해준다.

 

 

 

이런식으로 코드와 실행 결과 및 기타 내용 등을 정리해 파일로 저장할 수 있도록 환경을 제공해주는게 주피터 노트북이다.

앞으로 파이썬을 이용해 머신러닝 등을 실습할 예정인데 이때 주피터 노트북을 활용해 정리해볼 예정이다.

 

 

끝.
