tf.config.experimental.set_memory_growth

View source on GitHub

Set if memory growth should be enabled for a PhysicalDevice.

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.
