title: how to convert .pts or .npy file into .ply or .h5 file?
body: <p>I have 3d point cloud data as .npy file and .pts data.</p>
  
  <p>To use these data for 3d classification neural net, I have to change these data to .h5 file.</p>
  
  <p>So, first I am trying to convert .npy or .pts file to .ply file using python.</p>
  
  <p>Could you refer to me example codes  or help me for converting file format?</p>
  
  <p>Also, I will really appreciate for ways to  convert .ply to .h5 format..</p>
