Keras version and ?tensorflow? backend version?

[AlexanderMath]

Which version of keras was used for this implementation? Also, which backend was used, and which version of the backend?

I got the following to work after a few attempts

conda create --name keras
python -m pip install keras==1.2.2
python -m pip install tensorflow==1.13.0-rc1

I'm pretty convinced these were not the versions used when developing the project, but it seems to work. I got issues with renaming of Merge layer from Keras and batch_matmul in TensorFlow. The versions above apparently had the same naming conventions as the developed code, I didn't have to change anything in the code to run with these.

Furthermore, if one use an updated version of Pickle there is an error when loading the histopathology dataset.
I found the following change fixes the issue:

data = pickle.load(f) # previous 
data = pickle.load(f, encoding='latin1') # new
