AttributeError: 'Function' object has no attribute 'outputs'

[Roseblac]

When I tried to run run.py --gpu=gpu_num --dset=mnist，this error came out.

Each dataset has different types of 'AttributeError'
for example: for dataset cc : the error is "AttributeError: 'TensorVariable' object has no attribute 'get_shape'"

My OS is: ubuntu 16.04

Please give me some advice to solve it.Thanks.
If you need other information, I will upload later.

Hi, thanks for raising this issue. I did not mention this, but our code presently works only with the tensorflow backend in keras. It seems like you might be using Theano. Please take a look here, and change the backend appropriately

[Roseblac]

Thanks!.I was very appreciated that you could help me solve it.
I had changed the backend in keras and it did works. But another Attribute Error came out. I had tried different datasets and they all had this error.
How can I solve this problem? It seems my environment has some problems but I did not know how to reset it. : (

AttributeError: 'NoneType' object has no attribute 'stop_training'

[lihenryhfl]

This seems to stem from a change in how models are created in the newest version of Keras. This is circumvented by simply checking if self.model is None before trying to access stop_training. I've made this change and pushed it. Things should work now. Can you try running the model again with the new code?

[Roseblac]

Thanks very much for the new code.Yes,it works.But only reuters and mnist. When i tried to run with the cc and semisup dataset, it will cause the "ValueError".

So i started to search for the variable "biased", But it was in the keras package. and I am not sure about what part of my environment has problems. Is that still the problem of the version of keras? How can I solve this problem? Thanks for your help again. ：）

[weishao6hao]

I also had the same problem. The most important thing is that the dataset cannot converge.

[Roseblac]

since it gave me the location of the original definition, I was not sure which variable was the key problem. Do you have any ideas about that? Thanks. :)

[lihenryhfl]

Strange, I can't reproduce your issue. I've tried running on Ubuntu 14.04, Ubuntu 17.10, and macOS 10.13.3, tensorflow versions 1.4-1.7, and the latest version of keras. Any way you guys could try running the code on a different machine?

[Roseblac]

Apologize for my answer is late. I will try to use a different machine. But I don't know why it cames out such a error about tf.variable. Thank you.

I had the same problem.Have you solved it now?
