title: Jupyter notebook - "No module named keras", but it was imported
body: <p>I'm running Jupyter notebook in a conda virtual environment (Ubuntu), and first entered:</p>
  <pre><code>import tensorflow as tf
  from tensorflow import keras
  from keras.wrappers.scikit_learn import KerasClassifier
  </code></pre>
  <p>As you can see in the image below, it appears that keras has been imported.  However, when I try to import a function from keras.wrappers.scikit_learn I get an error message suggesting that keras hasn't been imported.  What am I missing here??</p>
