tf.compat.v1.config.experimental.set_memory_growth

tf.config.experimental.set_memory_growth(
    device, enable
)

If memory growth is enabled for a PhysicalDevice, the runtime initialization will not allocate all memory on the device. Memory growth cannot be configured on a PhysicalDevice with virtual devices configured.

For example:

physical_devices = tf.config.list_physical_devices('GPU')
try:
  tf.config.experimental.set_memory_growth(physical_devices[0], True)
except:
  # Invalid device or cannot modify virtual devices once initialized.
  pass

Args
device	PhysicalDevice to configure
enable	(Boolean) Whether to enable or disable memory growth

Raises
ValueError	Invalid PhysicalDevice specified.
RuntimeError	Runtime is already initialized.
