Setup Tensorflow Object Detection API for minium memory usage

Change Line 62 in "model_main.py" from

config = tf.estimator.RunConfig(model_dir=FLAGS.model_dir)

to

config = tf.ConfigProto()
config.gpu_options.allow_growth = True
config.gpu_options.per_process_gpu_memory_fraction = 0.1
config = tf.estimator.RunConfig(model_dir=FLAGS.model_dir,
                                session_config=config)

this way it should minimize your memory needs
