how to calculate a Mobilenet FLOPs in Keras

Question

run_meta = tf.RunMetadata()
enter codwith tf.Session(graph=tf.Graph()) as sess:
K.set_session(sess)


with tf.dev         


        

Answer 1

This is working for me in TF-2.1:

def get_flops(model_h5_path):
    session = tf.compat.v1.Session()
    graph = tf.compat.v1.get_default_graph()


    with graph.as_default():
        with session.as_default():
            model = tf.keras.models.load_model(model_h5_path)

            run_meta = tf.compat.v1.RunMetadata()
            opts = tf.compat.v1.profiler.ProfileOptionBuilder.float_operation()

            # Optional: save printed results to file
            # flops_log_path = os.path.join(tempfile.gettempdir(), 'tf_flops_log.txt')
            # opts['output'] = 'file:outfile={}'.format(flops_log_path)

            # We use the Keras session graph in the call to the profiler.
            flops = tf.compat.v1.profiler.profile(graph=graph,
                                                  run_meta=run_meta, cmd='op', options=opts)

            return flops.total_float_ops
