virtualenv의 Python 2.7에 numpy를 설치하는 방법에 대한 제안이 있으십니까?

참고:
Cygwin의 Python3 버전은 3.6이며 pypi numpy는 아직 3.6에 대한 준비가 되지 않은 것 같습니다.

편집 1:

에 대한 답변으로마체리님의 의견에 따르면 numpypip3 및 pip2에서 제거하고 numpyCygwin의 setup.exe에서 Python 3 및 Python 2용으로 설치했습니다.
다음은 나중에 numpy를 가져오려고 할 때 발생하는 오류입니다.

답변1

python2-numpycygwin 설정으로 패키지를 설치하십시오 . 설치하는 데 pip가 필요하지 않습니다.

python2 -c "import numpy"나를 위해 일합니다.
문제가 발생한 것 같으면 진행 중인 경로 lapack_lite를 확인하세요 ./usr/lib/lapack/

$ cygcheck -l liblapack0
/etc/profile.d/lapack0.csh
/etc/profile.d/lapack0.sh
/usr/lib/lapack/cygblas-0.dll
/usr/lib/lapack/cyglapack-0.dll


 $ cygcheck /usr/lib/python2.7/site-packages/numpy/linalg/lapack_lite.dll | grep -v Windows
E:\cygwin64\lib\python2.7\site-packages\numpy\linalg\lapack_lite.dll
  E:\cygwin64\bin\cygwin1.dll
  E:\cygwin64\lib\lapack\cyglapack-0.dll
    E:\cygwin64\bin\cyggcc_s-seh-1.dll
    E:\cygwin64\bin\cyggfortran-3.dll
      E:\cygwin64\bin\cygquadmath-0.dll
    E:\cygwin64\bin\cygblas-0.dll
  E:\cygwin64\bin\libpython2.7.dll

그렇지 않으면 lapack 라이브러리가 작동하지 않습니다.
