why this code only in discriminator, but not in generator?:
with tf.variable_scope(tf.get_variable_scope(), reuse=reuse_variables) as scope:

Am I wrong, or in your current implementation you are not updating the betas and the gammas of the batch normalization layers (during of course the training) ?

Bests,

I have a database which consist of low-dose pictures, how should I train them with this algorithm?

Help~!!!!

Error Tensor name "g_b1/beta" not found in checkpoint files pretrained-model/pretrained_gan.ckpt when loading pre-trained model, can anyone help?

Hello, please maybe could you help me? I had a running for running, I tried to figurate how to solve but I could not, I tried also with Python 2, 3.5, 3.6, And Tensorflow 1 and 1.1
