numpy及scipy安裝

numpy安裝

可能會提示你先升級pip python -m pip install --upgrade pip

方法1：用命令pip install numpy 直接安裝

C:\Users\siyu\AppData\Local\Programs\Python\Python35\Scripts>pip install numpy
Collecting numpy
  Downloading numpy-1.12.1-cp35-none-win_amd64.whl (7.7MB)
    100% |████████████████████████████████| 7.7MB 86kB/s
Installing collected packages: numpy
Successfully installed numpy-1.12.1

方法2：下載安裝包用pip安裝

可能會遇到如下報錯

C:\Users\siyu\AppData\Local\Programs\Python\Python35\Scripts>pip3 install "numpy-1.11.2"
Collecting numpy-1.11.2
  Could not find a version that satisfies the requirement numpy-1.11.2 (from versions: )
No matching distribution found for numpy-1.11.2

numpy包下載地址Numerical Python
將安裝包放在Python安裝目錄的Script文件夾下，我的是
C:\Users\siyu\AppData\Local\Programs\Python\Python35\Scripts
然後在上述文件路徑下打開cmd窗口，輸入pip install "numpy-1.11.2" 聽說要注意雙引號。

方法3：直接下載.exe安裝軟件安裝

也是推薦的安裝方法之一，但是某些新版本的官網上好像沒有發佈.exe

Scipy安裝

直接pip install scipy會下面的報錯，這是由於numpy相關的whl的問題，但是先pip安裝whl也沒用，可以在上述網站直接下載scipy+whl解決

C:\Users\siyu\AppData\Local\Programs\Python\Python35\Scripts>pip install scipy
