Python 외부 라이브러리 numpy 설치

Numpy

   -> Numerical Python 의 줄임말로 고성능 수치계산을 위해 만들어진 파이썬 패키지이다.

vertor, metrix, n-th array 등의 데이터 분석의 필수 도구이다.

파이썬 버전이 3.6 이면 cp36

Windows 64bit 이면 adm64

설치 명령어 : python -m pip install {다운로드 파일 경로}

ex) python -m pip install D:\numpy-1.15.0+mkl-cp36-cp36m-win_amd64.whl

------------------------------------------------------------------------------------------------------

E:\Work_File\numpy>python -m pip install "numpy-1.15.0+mkl-cp36-cp36m-win_amd64.whl"

numpy-1.15.0+mkl-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform.

You are using pip version 9.0.3, however version 18.0 is available.

You should consider upgrading via the 'python -m pip install --upgrade pip' command.

-----------------------------------------------------------------------------------------------

pip 버전이 낮어 설치가 안된단다.. 이런..

pip 버전 확인은 아래와 같다.

pip --version

그래서 업그레이드 했다.

python -m pip install --upgrade pip

--------------------------------------------------------------------------------------------

E:\Work_File\numpy>python -m pip install --upgrade pip

이런. 권한이 없단다... 리눅스 같았으면 바로 될것인데. 윈도우니깐 폴더의 권한이 없어서 안된것이다.

귀찮다.

everyone 권한을 아래 폴더에 Full 로 줘버렸다.

C:\Program Files\Python36 

결론은 업그레이드 완료.

설치 또한 완료되었다.

E:\Work_File\numpy>python -m pip install "numpy-1.15.0+mkl-cp36-cp36m-win_amd64.whl"
