title: Tensorflow Object Detection: use Adam instead of RMSProp
body: <p>I'm training a CNN with this [.config file][1]:</p>
  
  <blockquote>
  <pre><code>rms_prop_optimizer: {
      learning_rate: {
        exponential_decay_learning_rate {
          initial_learning_rate: 0.004
          decay_steps: 800720
          decay_factor: 0.95
        }
      }
     momentum_optimizer_value: 0.9
     decay: 0.9
     epsilon: 1.0
  }   
  </code></pre>
    
    <p>}<br>
    As you can see there is a rms_prop as optimizer. What if I would like to use Adam? How am I supposed to edit this file?</p>
