title: Cannot import name 'SGD' from 'keras.optimizers' when importing talos
body: <p>I am trying to import talos python module using <code>import talos</code>
  this is the error I get:</p>
  <blockquote>
  <p>ImportError: cannot import name 'SGD' from 'keras.optimizers'</p>
  </blockquote>
  <p>I have solved the same error message before when I used <code>from keras.optimizers import Adam,Nadam, SGD</code> changing the code to <code>from tensorflow.keras.optimizers import Adam,Nadam, SGD</code>. However, the error message I get now is within the internal talos import command. talos 0.4.8, keras 2.2.4, tensorflow 2.6.0
  Thank you</p>
