title: Do I need to install keras 2.0 seprately after installing tensorflow 1.3?
body: <p>I just upgraded my tf from 1.0 to tf 1.3 (pip install --upgrade tensorflow) . I know keras 2.0 became part of tensorflow since tf version 1.2. However, when I import keras and check its version it still shows 1.2. Am I supposed to upgrade keras also? if so, then what does "<a href="https://blog.keras.io/introducing-keras-2.html" rel="noreferrer">the Keras API will now become available directly as part of TensorFlow, starting with TensorFlow 1.2</a>" mean? </p>
