title: iPython notebook not loading
body: <p>So my iPython notebook comes up in my browser (chrome) and when I open my specific notebook a new tab opens. However the work does not load up! The page also freezes. Is this an iPython issue or something wrong with the file? Was working yesterday. I've restared comp etc. but no luck</p>
  
  <p>Update: just tried renaming notebook to open again with no luck</p>
  
  <p>Update 2: One has now shown up - but can't do anything with it! Is iPython simply extremely extremely slow...</p>
