also having issues with the demo

[ClaireleNobel]

This is what I get on step 2. I tried working with the fixes that people suggested on the other posts, but have still not had any luck. Any suggestions would be greatly appreciated!

Does this demo occur when you run the demo notebook?

Did you try restarting the notebook and running all cells in order?

It sounds like for some reason the same variable is being created twice when you run it.

[ClaireleNobel]

Yes, this happens when I'm running on Jupyter. I just tried restarting the notebook and running the cells in order... but this happens when I'm on just the second cell... I have attached a screenshot so that you can see colours. I really hope this works!

[brannondorsey]

I believe this is an error that occurs when you are running with tensorflow version >=1.0. I received this error, downgraded to tensorflow 0.12.0, and that fixed it.

pip uninstall tensorflow # tensorflow-gpu
pip install tensorflow==0.12 # tensorflow-gpu==0.12

[tnarik]

Yes, the issue is the version of tensorflow. It would be great if the project included a requirements.txt file or similar to ensure consistency.

Failing this, you can easily to TensorFlow 1.1.0 at least (didn't try my modification on the new 1.2).

[ishandutta2007]

@tnarik @brannondorsey @WeiHan3 if you have succeeded in training it now, can you please share the model.

[aryachiranjeev]

i am running it on colab and facing this error
@tnarik can you help with this
