6 years ago Make sure your tensorflow version is correct (should be 1.0.0 -- see README)

6 years ago I got the same error and this fixed it for me. It's a very silly issue it seems. If you're running your code in a jupyter notebook (as I was), the variables persist in the environment. So if you run once, and the code breaks, and you try to run it again the variable is still in memory and can't be re-created.
Simply restart your kernel and re-run, it'll work fine. Hope this helps! :)

6 years ago If your tensorflow version is greater than 1.0, you need to add reuse to specify whether to repeat the call.like this：
def discriminator(self, image, K, disc_params, train=True, reuse=False):
with tf.variable_scope("discriminator", reuse=reuse) as scope:
...Of course, you need to add reuse when you use it.
d_probs, d_logits, _ = self.discriminator(self.inputs, self.K, disc_params,reuse=False)
...
d_probs_, d_logits_, _ = self.discriminator(self.generator(self.z[:, :, gi % self.num_gen], gen_params),
self.K, disc_params, reuse=True
...The same operation for generator.Hope this helps!
