UPDATE 2

関連しているが、あなたが permission deniedエラーがある場合、としてみてください

tecsadmin@BLITZ:~$ pip freeze | grep numpy 
numpy==1.11.0 
tecsadmin@BLITZ:~$ pip freeze | grep scipy 
scipy==0.17.1 
tecsadmin@BLITZ:~$ pip freeze | grep scikit-learn

Answer 1

わからない sudo pip install -U numpy scipy scikit-learn

また、私は、sudoでプレイしているあなたがそうあなたがいけない https://virtualenv.pypa.io/en/stable/のpython仮想環境を使用することをお勧め

はpip freeze

$ pip freeze | grep numpy 
$ numpy==1.9.2 

インストールの実行、それがsuccesfuly

をインストールされている場合、あなたが本当にチェックする方法を再確認するために、許可

Answer 2

エラー13のアクセス権が拒否されたライブラリをインストールしていません。

sudo pip install numpy scipy scikit-learn
