title: Get the recall over the epochs in keras
body: <p>I am compiling my model with</p>
  <pre><code>metrics=[&quot;accuracy&quot;, keras.metrics.Recall()]
  </code></pre>
  <p>as stated in the documentation. But when I try to obtain it after I've trained my model I get a key_error &quot;recall&quot;. Both versions,</p>
  <pre><code>recall = estimator_bio.history[&quot;Recall&quot;]
  recall = estimator_bio.history[&quot;recall&quot;]
  </code></pre>
  <p>result in</p>
  <pre><code>KeyError: 'Recall'
  </code></pre>
  <p>While</p>
  <pre><code>accuracies = estimator_bio.history[&quot;accuracy&quot;]
  </code></pre>
  <p>works. What is the keyword for the recall?</p>
