title: Pyinstaller created exe file can not load a keras nn model
body: <p>My python scrip includes:</p>
  
  <pre><code>from keras.models import model_from_json
  model = model_from_json(open("test.json").read())
  model.load_weights("test.h5")
  model.compile(loss="mean_squared_error", optimizer = "adam")
  </code></pre>
  
  <p>Then, I created  an exe file using pyinstaller from aforementioned script. The exe file can not load the saved model. Any thought on that would be appreciated. </p>
