I'm trying to install PlaidML with a specific environment but the correct version of Keras and Tensorflow aren't installed or the correct versions are installed but the PlaidML backend is not used.
My requirements.txt file is
scikit-learn
scikit-image
matplotlib
seaborn
ipython
jupyter
scipy
numpy
pandas
pillow
pydot
coremltools==3.0
plaidml==0.6.4
plaidbench==0.6.4
keras==2.2.4
tensorflow==1.14
My Python code starts with
import os
os.environ["KERA_BACKEND"] = "plaidml.keras.backend"
import keras
Are there any examples of how to set up PlaidML using specific libraries?
