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 notebooks

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.
