How to know which .whl module is suitable for my system with so many?
<p>We have so may versions of wheel. 
How could we know which version should be installed into my system?
I remember there is a certain command which could check my system environment.
Or is there any other ways?</p>

<p>scikit_learn-0.17.1-cp27-cp27m-win32.whl
scikit_learn-0.17.1-cp27-cp27m-win_amd64.whl
scikit_learn-0.17.1-cp34-cp34m-win32.whl
scikit_learn-0.17.1-cp34-cp34m-win_amd64.whl
scikit_learn-0.17.1-cp35-cp35m-win32.whl

<p>You don't have to know.  Use <code>pip</code> - it will select the most specific wheel available.</p>
