starting conda & jupyter notebook on mac

https://docs.conda.io/projects/conda/en/latest/user-guide/getting-started.html

Getting started with conda — conda 4.11.0.post8+f60f0f16 documentation

 

공식 문서 그대로 따라갔다 

 

 

1. conda 설치 

https://docs.anaconda.com/anaconda/install/mac-os/

Installing on macOS — Anaconda documentation

https://www.anaconda.com/products/individual#macos

Anaconda | Individual Edition

두번째 페이지에서 설치 패키지를 다운 받을 수 있다. 

첫번째 페이지에서는 설치 과정을 설명함 

 

설치를 하는데 5분 정도 걸림 

 

 

2.  conda 설치 확인 

Managing conda

Verify that conda is installed and running on your system by typing:

conda --version

Conda displays the number of the version that you have installed. You do not need to navigate to the Anaconda directory.

EXAMPLE: conda 4.7.12

Note

If you get an error message, make sure you closed and re-opened the terminal window after installing, or do it now. Then verify that you are logged into the same user account that you used to install Anaconda or Miniconda.

 

설치를 완료하면 터미널을 완전 끄고 다시 킨다음 

conda --version을 쳐보자 

2021년 12월 7일 새로 설치하면 4.10.3 버전이 나온다 

 

 

터미널을 완전 끄고 다시 키는게 중요하다 

 

 

3. conda 실행 

conda는 가상환경을 만드는 패키지다 

가상환경 만드는 명령어는 conda create이다. 

conda create -n [가상환경이름] [패키지]

공식 문서는 

conda create -n snowflakes biopython 

을 썼다. snowflakes라는 이름의 환경에 biopython을 설치한다는 뜻 

 

내 경우에는 강의 대로 따라가서 upstage라는 이름을 써서 실행

시간 조금 흐르고 설치가 환료된다 

 

# To activate this environment, use
#
#     $ conda activate upstage
#

위에 써져 있듯이 가상환경을 쓸려면 이 명령어를 치라고 나온다 

그럼 conda activate를 해보자 

 

 

4. conda  activate

conda activate upstage 
activate upstage (x)

밑에 꺼로 하니까 제대로 안들어가진다 

치면 아무 출력 없이 끝이 난다

 

(base) ➜  ~ activate upstage
(base) ➜  ~ conda install numpy

(base) ➜  ~ conda install jupyter
Collecting package metadata (current_repodata.json): done
Solving environment: done

# All requested packages already installed.

 위는 모르고 base에다가 설치한 경우 ㅜㅜ 

이건 가상환경을 제대로 쓴게 아니다 

 

(base) ➜  ~ conda activate upstage
(upstage) ➜  ~ conda install numpy
Collecting package metadata (current_repodata.json): done
Solving environment: done

옆에 (base)가 아까 설정한 이름 (upstage)로 바뀌어야 

제대로 가상환경 안으로 들어온 것이다 

 

여기서 필요한 패키지를 설치하자 

 

5. conda install 

conda install numpy 

conda install jupyter

 

Proceed ([y]/n)? ㅛㅛ y

이렇게 설치 환료 

 

그럼 코드 폴더로 가서 jupyter notebook 명령어를 친다 

 

[I 16:42:52.032 NotebookApp] Jupyter Notebook 6.4.4 is running at:
[I 16:42:52.032 NotebookApp] http://localhost:8888/?token=af62593d4bd28aa47c07e00f6d8ab2a689d2c9bddc4c3aa9
[I 16:42:52.032 NotebookApp]  or http://127.0.0.1:8888/?token=af62593d4bd28aa47c07e00f6d8ab2a689d2c9bddc4c3aa9
[I 16:42:52.032 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[C 16:42:52.052 NotebookApp]

    To access the notebook, open this file in a browser:
        file:///Users/a/Library/Jupyter/runtime/nbserver-9652-open.html
    Or copy and paste one of these URLs:
        http://localhost:8888/?token=af62593d4bd28aa47c07e00f6d8ab2a689d2c9bddc4c3aa9
     or http://127.0.0.1:8888/?token=af62593d4bd28aa47c07e00f6d8ab2a689d2c9bddc4c3aa9

  return _iterencode(o, 0)

그럼 해당 폴더에 있는 코드를 jupyter notebook로 실행할 수 있다 

 

이렇게 localhost:8888 에 실행됨 

신기~

 

ipynb에서 더 빛을 발할 것으로 예상됨
