title: apt-get install python files or just pip install?
body: <p>I noticed that i was reading a book mentioning to install numpy and opencv by way of apt-get</p>
  
  <pre><code>apt-get install python-numpy python-opencv
  </code></pre>
  
  <p>but i can find these in pip by:</p>
  
  <pre><code>pip search numpy
  </code></pre>
  
  <p>so this begs me to ask the question:</p>
  
  <p>How do these package managers work?  If i run <code>pip install numpy</code> will it install to the same directory as <code>apt-get install python-numpy</code>?</p>
  
  <p>I was curious as to what the best way to do it would be if they are installed into different paths.</p>
  
  <p>I want to say "just do it in pip" but its hard to justify since I dont know how each of the different package managers install things.  Are they installed into different directories, but both are on the path to accessible python modules?</p>
