How to use K.get_session in Tensorflow 2.0 or how to migrate it? : <pre><code>def __init__(self, **kwargs):
    self.__dict__.update(self._defaults) # set up default values
    self.__dict__.update(kwargs) # and update with user overrides
    self.class_names = self._get_class()
    self.anchors = self._get_anchors()
    self.sess = K.get_session()
</code></pre>

<p>RuntimeError: <code>get_session</code> is not available when using TensorFlow 2.0.</p>
