Simple mnist example for using keras to save tracing info with TF

keras_tracing.sh

#Install requirements.
pip install virtualenv
virtualenv --python=/usr/bin/python2.7 keras_tracing
source keras_tracing/bin/activate 
cd keras_tracing/
pip install keras 
pip install -i https://pypi.anaconda.org/intel/simple tensorflow    

#Clone mnist sample code
git clone https://github.com/ravi9/keras-trace-example.git
cd keras-trace-example

#Train a MNIST model
python mnist_train.py

#Run inference, model.predict() and save timeline tracing info
python mnist_inference.py

#The above command will save Tensorflow trace to: ./timeline_trace.json
#To view the trace:
#(1) Open Chrome browser.
#(2) Go to this url -- chrome://tracing
#(3) Click the load button.
#(4) Load the file ./timeline_trace.json
