title: Why can't i pass mode to the discriminator function in tensorflows GANEstimator?
body: <p>When using the GANEstimator in the tensorflow library, I can only pass the mode to the generator function but not the discriminator function. This means I can not perform batch normalisation or dropout in the discriminator. Is there a reason why this is not allowed? Will this be changed in the future?</p>
