segan variable does not exist

When I run the main.py,I find that ValueError: Variable d_model/d_block_0/downconv/W/RMSProp/ does not exists.

Could you help me? Best regards

@djjandXMU I am also getting the same error. I have tried https://stackoverflow.com/questions/43183850/tensorflow-valueerror-variable-does-not-exist-or-was-not-created-with-tf-get-v but nothing seems to work. Did you get the solution?? Best Regards

The given error can be solved by changing a fraction of a code... In main.py just change the optimizer function from tf.Adamoptimizer() to tf.GradientDescentOptimizer(). but the tradeoff to change main.py is traning time.

model.py line144 self.d_opt = d_opt.apply_gradients(avg_d_grads) model.py line145 self.g_opt = g_opt.apply_gradients(avg_g_grads) Maybe you can replace line144-145 with the following code. with tf.variable_scope(tf.get_variable_scope(), reuse=tf.AUTO_REUSE): self.d_opt = d_opt.apply_gradients(avg_d_grads) self.g_opt = g_opt.apply_gradients(avg_g_grads)

@AnilMandliya @djjandXMU i have fixed this issue in my fork: https://github.com/fcakyon/segan

@fcakyon Sorry to bother you, I used your fork to train this model on a no gpu machine，When I run train_segan.sh，I met the following error: tensorflow.python.framework.errors_impl.NotFoundError: No registered 'TemporaryVariable' OpKernel for XLA_CPU devices compatible with node {{node device_1/gradients/AddN_14/tmp_var}} Could you please help me figure out what problem happens? Any reply will be appreciated.
