FailedPreconditionError: Attempting to use uninitialized value spectral_net_learning_rate

[wangemm]

When I tried to run python3 run.py，this error came out.
ERROR：

I have exactly the same problem, please keep me updated if you have found a solution to it.

Hi, thanks for using SpecrtalNet, which version of TensorFlow are you using?

[wangemm]

Thanks. I run the code on tensorflow1.14.0 and 1.15.0, both get the same error.

[CatherineTaelman]

For me, the error was resolved by changing the variable initialization in the SpectralNet class (networks.py) to this:
K.get_session().run(tf.initialize_all_variables())

[wangemm]

I changed the variable initialization in networks.py:
# K.get_session().run(tf.variables_initializer(self.net.trainable_weights))
K.get_session().run(tf.initialize_all_variables())
It ran, but can`t reproduce paper results.
Results: ACC0.395 NMI0.315

[CatherineTaelman]

@wangemm do you have any update on reproducing the paper results? I have the same issue. I can only achieve the mentioned results when I choose knn affinity and use code space. For the other options I did not succeed in reproducing the results.

[wangemm]

@CatherineTaelman I also choose knn affinity and use code space. And get the results:ACC0.395 NMI0.315.

This is old, but have you made sure to use keras==2.3 as well? We realized that this was an important choice.

[mertsener057]

hi, i have same issue im using keras==2.3 and tensorflow version 1.5
K.get_session().run(tf.variables_initializer(self.net.trainable_weights)) making error .
i tried K.get_session().run(tf.initialize_all_variables()) give low acc and nmi. how can i fix?
Thank you.
Can we use global initializer instead do you have any idea?

Thankyou for the research on SpectralNet and this opensourse code. I have the same question as @mertsener057 and some of the users' above. While I am now have two questions briefly:

1. Why the environment or the versions of packages contribute so much to the performances of this model?
2. Is it possible for me to rewrite the code to make it adaptive to the latest versions of tensorflow or the other ML structures used in SpectralNet and get the same performances as your paper presented?
   Waiting for your advice with appreciation and respect!
