  <pre><code>Error in keras::load_model_hdf5(file_path) : 
    The h5py Python package is required to save and load models
  </code></pre>
  
  <p>I have tried to reinstall h5py package from terminal. I have also installed <code>keras</code> package. I can import h5py package in pyrthon, but Rstudio doesn't recognize it somehow.</p>
