title: Read only mode in keras
body: <p>I have cloned human pose estimation keras model from this link <a href="https://github.com/michalfaber/keras_Realtime_Multi-Person_Pose_Estimation" rel="noreferrer">human pose estimation keras</a> </p>
  
  <p>When I try to load the model on google colab, I get the following error</p>
  
  <p>code</p>
  
  <pre><code>from keras.models import load_model
  model = load_model('model.h5')
  </code></pre>
  
  <p>error</p>

  <p>Can someone please help me understand this read-only mode? How do I load this model?</p>
