I ran into an issue while trying to complete these instructions to use a tumor classifying machine learning model on github: https://github.com/CBIIT/NCI-DOE-Collab-Pilot1-Normal-Tumor-Pair-Classifier/tree/master/Pilot1/NT3

I did the following: 

git clone https://github.com/CBIIT/NCI-DOE-Collab-Pilot1-Normal-Tumor-Pair-Classifier
conda env create -f environment.yml -n nt3 
conda activate nt3 
cd Pilot1
cd NT3
python nt3_baseline_keras2.py

But I am getting this error:

Using TensorFlow backend.

Does anyone else get this issue? I tried uninstalling and reinstalling tensorflow and tensorboard but this results in more compatibility errors.
