allow gpu memory growth tensorflow code example

Example 1: config allow growth tensorflow

config = tf.ConfigProto()
config.gpu_options.allow_growth=True
sess = tf.Session(config=config)

Example 2: tensorflow allow growth

gpus = tf.config.experimental.list_physical_devices('GPU')
if gpus:
  try:
    tf.config.experimental.set_virtual_device_configuration(
        gpus[0],
        [tf.config.experimental.VirtualDeviceConfiguration(memory_limit=1024*6)])
    logical_gpus = tf.config.experimental.list_logical_devices('GPU')
    print(len(gpus), "Physical GPUs,", len(logical_gpus), "Logical GPUs")
  except RuntimeError as e:
    # Virtual devices must be set before GPUs have been initialized
    print(e)
