tf.contrib.gan.features.clip_variables( optimizer, variables, weight_clip )
Modifies an optimizer so it clips weights to a certain value.
optimizer: An optimizer to perform variable weight clipping.
variables: A list of TensorFlow variables.
weight_clip: Positive python float to clip discriminator weights. Used to enforce a K-lipschitz condition, which is useful for some GAN training schemes (ex WGAN: https://arxiv.org/pdf/1701.07875).
An optimizer to perform weight clipping after updates.
weight_clipis less than 0.
