wie numpy für neuere Python-Version

Question

Ich bin mit Python 3.5.2 installieren und

>>> import numpy 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
ImportError: No module named 'numpy' 

jedoch ausgeführt werden soll, wenn ich

ola@station:~$ pip install numpy 
Requirement already satisfied: numpy in /usr/lib/python2.7/dist-packages 
ola@station:~$ 

in einem Terminal überprüfen Warum ich so habe viele verschiedene Pip's?

ola@station:~$ pip 
pip  pip2 pip2.7 pip3 pip3.4 pip3.5 pip3.6 

und wenn ich versuche, pip3.4 zu verwenden ich

ola@station:~$ pip3.5 install numpy 
Traceback (most recent call last): 
    File "/usr/local/bin/pip3.5", line 6, in <module> 
    from pkg_resources import load_entry_point

pkg_resources.DistributionNotFound: The 'pip==8.1.2' distribution was not found and is required by the application

Sie haben ein Pip für jede Version von Python. Wenn Sie numpy für python3.5 installieren möchten, können Sie verwenden:

pip3.5 install numpy
