title: How to completely uninstall opencv ubuntu?
body: <p>I am installing caffe and I think I screwed up my install by having multiple versions of OpenCV. Now i don't know what i did on my own but nothing seems to work right. So my safest bet is to do a complete utter uninstall of opencv. How do i do that help thanks ?</p>
  
  <p>I would like to install python after that using conda</p>
  
  <p>I followed this thread <a href="https://stackoverflow.com/questions/9276169/removing-all-installed-opencv-libs/38217001#38217001">Removing all installed OpenCV libs</a></p>
  
  <p>although when i typed <code>$&gt; sudo find / -name "*opencv*" -exec rm -i {} \;</code></p>
  
  <p>ubuntu still keeps asking me for permission to remove every file which is annoying. how do i tell ubuntu to remove it all ?</p>
