ValueError: Variable d_conv_dis_1_a/w/Adam/ does not exist, or was not created with tf.get_variable(). Did you mean to set reuse=tf.AUTO_REUSE in VarScope?

Solved the issue by adding with tf.variable_scope(tf.get_variable_scope(),reuse=False): Although this didn't solve the issue completely, then added the scope definition for generator and discriminator network.

Raising PR for the fixes !! https://stackoverflow.com/questions/43183850/tensorflow-valueerror-variable-does-not-exist-or-was-not-created-with-tf-get-v
