title: Python3, how to install numpy on CentOS 7?
body: <p>I'm working with <strong>Python 3.5.1</strong> on a computer having <strong>CentOS Linux</strong> release 7.3.1611 (Core) operating system. </p>
  
  <p>I have to install the <code>numpy</code> package.</p>
  
  <p>I tried to follow <a href="https://stackoverflow.com/questions/17443354/install-numpy-on-python3-3-install-pip-for-python3">these instructions</a>, by running the command:</p>
  
  <pre><code>sudo yum -y install python34-setuptools
  </code></pre>
  
  <p>Unfortunately, I got the following error:</p>
  
  <pre><code>Transaction check error:
    file /usr/lib64/libpython3.so from install of python34-libs-3.4.5-4.el7.x86_64 conflicts with file from package python3-libs-3.3.2-12.el7.nux.x86_64
  </code></pre>
  
  <p>Any idea on how to solve this problem? Thanks</p>
  
  <p><strong>EDIT</strong>: On my machine, I have both Python2.7 and Python3.5, and I want to keep them both</p>
