머리말

저자는 오늘 이상한 문제에 직면했는데, Python을 3.8에서 3.10으로 업그레이드한 후 잘 작동하고 있습니다. 하지만 오늘 특정 기능을 실행하면 항상 응답 없이 종료됩니다. 처음에는 pandas1.5.3을 2.0.0으로 업그레이드하는 문제인 줄 알았는데 당시 2.0pandas가 빠르게 실행되고 있어서 업그레이드를 하였으니 일단은 배제하자. 먼저 팬더를 최신 버전으로 업그레이드하세요. 버전 1.5.3으로 떨어뜨린 후에도 여전히 작동하지 않습니다. 동일한 코드를 Python3.8.16을 사용하여 다른 컴퓨터로 변경할 수 있으며 이 팬더를 최신 버전으로 업그레이드해도 괜찮습니다.

문득 파이썬 버전의 문제일지도 모른다는 생각이 들었습니다.

Anaconda는 이러한 난처함을 해결하기 위해 가상 환경을 지원하므로 더 낮은 버전의 Python 환경을 만들까 생각했습니다. 아래에서 해보지만 환경을 설치한 후에도 아직 별도로 설치해야 하는 라이브러리가 많으므로 나중에 부록으로 정리하도록 하겠습니다.

1. 가상 환경 생성

Anaconda는 가상 환경을 생성하고 관리하는 데 매우 편리하며 여러 Python 버전이 필요한 경우 conda 명령줄을 사용하여 다양한 가상 환경을 생성할 수 있습니다. 구체적인 단계는 다음과 같습니다.

생성하기 전에 현재 사용 가능한 가상 환경이 무엇인지 살펴보겠습니다.

conda info --envs

일반적으로 Anaconda가 설치되면 기본적으로 기본 환경이 있습니다. 결과는 다음과 같습니다.

(base) C:\Users\Administrator>conda info --envs
# conda environments:
#
base                  *  d:\ProgramData\anaconda3

python38 python=3.8.16 환경 만들기

conda create --name python38 python=3.8.16

환경 활성화

conda activate python38

환경 초기화(이 단계는 매우 중요합니다. 인터넷에 일반 자습서가 없습니다. 이 단계를 수행하지 않으면 나중에 notepad++로 Python을 실행할 때 오류가 보고됩니다.)

conda init

다음 프롬프트가 나타나면 init 명령을 실행하십시오.

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If using 'conda activate' from a batch script, change your
invocation to 'CALL conda.bat activate'.

To initialize your shell, run

    $ conda init <SHELL_NAME>

Currently supported shells are:
  - bash
  - cmd.exe
  - fish
  - tcsh
  - xonsh
  - zsh
  - powershell

See 'conda init --help' for more information and options.

IMPORTANT: You may need to close and restart your shell after running 'conda init'.

기타 관련 명령:
입력: conda list, 현재 가상 환경에 포함된 패키지를 확인할 수 있습니다.
입력: conda deactivate, 현재 활성화된 환경 종료 입력
: conda create --name new_env_name–clone old_env_name 복제하여 환경 사본 생성 입력
: conda rename -n old_name new_name, rename으로 환경 이름 바꾸기 입력
: conda remove -n env_name --all -y 지정된 이름으로 가상 환경 삭제

2. Python 가상 환경을 실행하기 위한 단축키 구성 Nodepad++

위에서 생성한 환경을 python38이라 부르기 때문에 명령어에 bat 파일을 만들기 위해서는 먼저 conda activate python38을 실행한다.

예를 들어 D:\ProgramData\anaconda3\Scripts\ 디렉토리에 activatepy38.bat를 생성하고 콘텐츠는 단 한 줄입니다.

conda activate python38

Notepad++를 열고 F5 키를 눌러 실행한 다음 입력 상자에 다음 명령을 붙여넣고 저장을 클릭한 다음 바로 가기 키를 선택합니다. 여기서는 Alt+E로 설정되어 있습니다. 그런 다음 확인을 클릭합니다.

cmd /k chdir /d $(CURRENT_DIRECTORY) & call D:\ProgramData\anaconda3\Scripts\activatepy38.bat & python $(FILE_NAME) & PAUSE & EXIT

다른 버전이 있으면 해당 이름으로 바꿉니다.

요약하다

오늘은 오랫동안 작은 기능을 던지고 있으며 Ta-lib 라이브러리 및 이전 휠 보물 창고를 설치할 때 여전히 오류가 보고됩니다: https://www.lfd.uci.edu/~gohlke/ pythonlibs를 다운로드할 수 없습니다. 다행스럽게도 Stock을 찾았습니다. 드디어 끝났습니다.

트렌드를 따라가는 것도 사실이지만, 각 버전의 파이썬이 안정적으로 동작하는 것이 맞아떨어져야 한다는 점을 여기서 말해야겠다. 테스트를 하셔도 상관없지만, 작업 환경으로서 더욱 주의하셔야 합니다!
