title: No OpKernel was registered to support Op 'DecodeJpeg' with these attrs on ios
body: <p>I have followed the steps from Tensorflow For Poets (<a href="https://codelabs.developers.google.com/codelabs/tensorflow-for-poets/#0/%22Link%22" rel="nofollow noreferrer">link</a>) to train my own dataset using tensorflow, and getting very good prediction result.This provides me retrained.py, label_images.py, retrained_graph.pb, retrained_labels.txt files.So i have my own model graph and label file.</p>
  
  <p>After that i have downloaded Tensorflow Example Project for iOS from github. The project runs successfully in iOS platform. but when i am using my own retrained_graph.pb, retrained_labels.txt file on behalf of examples model and label file , i am getting error as following -</p>
  
  <p>Errors :</p>
