title: Is there a Keras tuner for tensorflow 1.12 version? If no, what are the alternatives?
body: <p>I have my model implemented on TensorFlow 1.12. However, now I want to use Keras-tuner, which is available only for TensorFlow 2. I couldn't find any implementation of the tuner for the 1.12 version. Is it my only choice right now to rewrite my model to make it compatible with TensorFlow 2?</p>
