What does this PR do?
When the
tf.exp(self.w)operation is performed inside the call method, tf.GradientTape may fail to efficiently trace the path between the trainable variable list (model.weights) and the final loss. It may causeNonein objective function.So, I updated the method to control the weights using a positive constraint.
