I am getting the following error when attempting to run this application.

Any ideas as to what is going on (what I am doing wrong)?

I guess it's a tensorflow version problem. This repo seems dependent on TF-1.14. Did you run it on TF2?

[LeonLok]

Yes, the error could be due to the tensorflow version. Could you try running it with the same dependencies as mine and see if the same error still occurs?

[tomklaver1995]

Tensorflow version 2 can't use session. Try to change tf.Session to tf.compat.v1.Session to get the same result. Besides when you use Keras.get_session() change that to tf.compat.v1.keras.backend.get_session(). Good luck

I can not seem to get version 1 of tensorflow installed anymore. Does anyone know how to install tensorflow-gpu Version 1?

For example when I run - sudo pip3 install "tensorflow-gpu>=1.14,<2.0"
ERROR: Could not find a version that satisfies the requirement tensorflow-gpu<2.0,>=1.14 (from versions: 2.2.0rc1, 2.2.0rc2, 2.2.0rc3, 2.2.0rc4, 2.2.0, 2.2.1, 2.2.2, 2.3.0rc0, 2.3.0rc1, 2.3.0rc2, 2.3.0, 2.3.1, 2.3.2, 2.4.0rc0, 2.4.0rc1, 2.4.0rc2, 2.4.0rc3, 2.4.0rc4, 2.4.0, 2.4.1)
