title: Importing caffe results in ImportError: "No module named google.protobuf.internal" (import enum_type_wrapper)
body: <p>I installed Anaconda Python on my machine.  When I start the Python Interpreter and type "import caffe" in the Python shell, I get the following error:</p>
  
  <pre><code>ImportError: No module named google.protobuf.internal
  </code></pre>
  
  <p>I have the following files:</p>
  
  <pre><code>wire_format_lite_inl.h
  wire_format_lite.h
  wire_format.h
  unknown_field_set.h
  text_format.h
  service.h
  repeated_field.h
  reflection_ops.h
  message_lite.h
  message.h
  generated_message_util.h
  extension_set.h
  descriptor.proto
  descriptor.h
  generated_message_reflection.h
  generated_enum_reflection.h
  dynamic_message.h
  descriptor.pb.h
  descriptor_database.h
  </code></pre>
  
  <p>What files do I need so the import will work?  Is there an "internal.h" file that is required?</p>
