title: what's the difference between "import keras" and "import tensorflow.keras"
body: <p>I was wondering, what's the difference between importing keras from tensorflow using <code>import tensorflow.keras</code> or just pip installing keras alone and importing it using <code>import keras</code> as both seemed to work nicely so far, the only difference I noticed is that i get <code>Using TensorFlow backend.</code> in the command line every time I execute the one using keras.</p>
