title: Message type "caffe.LayerParameter" has no field named "input_param"
body: <p>I downloaded the latest caffe library today and build.</p>
  
  <p>Tested the library in python to run through a classification program in Python.</p>
  
  <p>In parsing the prototxt file, I have the error as <code>Message type "caffe.LayerParameter" has no field named "input_param"</code>.</p>
  
  <p>The error happened at <code>net = caffe.Net(model_def, model_weights, caffe.TEST</code>) .</p>
  
  <pre><code>.model_def = caffe_root + 'models/bvlc_reference_caffenet/deploy.prototxt'
   model_weights = caffe_root + 'models/bvlc_reference_caffenet/bvlc_reference_caffenet.caffemodel'
  
   net = caffe.Net(model_def,      # defines the structure of the model
                  model_weights,  # contains the trained weights
                  caffe.TEST)     # use test mode (e.g., don't perform dropout)
  </code></pre>
  
  <p>According to the discussion <a href="https://github.com/BVLC/caffe/issues/3947" rel="nofollow noreferrer">here</a>, the error is because of not using latest build.
  For me I used the latest build. How to fix the issue.</p>
