tf.config.experimental.set_memory_growth

TensorFlow 1 version View source on GitHub

Set if memory growth should be enabled for a PhysicalDevice.

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

Used in the guide:

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.
