We may want to be more conservative to enable people to use Keras 2 via tf.keras without having to install tf_keras:

  1. from tensorflow import keras
  2. if not hasattr(keras, "version"): then tf.keras is Keras 2. We use keras from TF.
  3. else: try to import tf_keras
  4. if not available: raise

import tf_keras as keras
except ImportError:
raise ImportError(
"Keras 2 requires the `tf_keras` package."
