This example demonstrates the use of TensorFlow/Keras callbacks to start and stop TAU timers.

Build TAU for use with TensorFlow; for example,

    ./configure -bfd=download -unwind=download -cuda=/path/to/cuda -pthread -python 
    make
    make install

Add the library directory containing tau.py to $PYTHONPATH; for example,

    export PYTHONPATH=$HOME/tau2/x86_64/lib/shared-pthread-python-cupti:$PYTHONPATH

 Run the iris example:

    python iris-callbacks.py
