title: Snapdragon Neural Processing Engine Installation
body: <p>I'm running source check_python_depends.sh as part of  Qualcomm's Sanpdragon Neural Processing Engine SDK. As part of the installation process I run the following command</p>
  
  <p>source check_python_depends.sh </p>
  
  <blockquote>
    <p>Checking for python-yaml: install ok installed
    WARNING: It appears the python module pyyaml is installed on this system using the apt-get distribution as well as pip. If you encounter errors, please use only one distribution.</p>
  </blockquote>
  
  <p>When I run apt-get remove pyyaml I receive the following</p>
  
  <blockquote>
    <p>E: Unable to locate package pyyaml</p>
  </blockquote>
  
  <p>Is there another name I should be looking for in Ubuntu?</p>
  
  <p>Similiarly I receive the following messages during installation suggesting they aren't in pip or installed via the global package management.</p>
  
  <ol>
  <li>dpkg-query: no packages found matching python-protobuf</li>
  <li>dpkg-query: no packages found matching python-sphinx</li>
  </ol>
  
  <p>Are the naming conventions between Ubuntu and PIP not harmonized creating so much ambiguity? Am I correct to assume if there is not a global requirement that I'm generally better off using a local pip installation?</p>
