tf.config.experimental.set_memory_growth

TensorFlow 2.0 version View source on GitHub

Set if memory growth should be enabled for a PhysicalDevice.

Aliases:

  • tf.compat.v1.config.experimental.set_memory_growth
  • tf.compat.v2.config.experimental.set_memory_growth
tf.config.experimental.set_memory_growth(
    device,
    enable
)

A PhysicalDevice with memory growth set will not allocate all memory on the device upfront. Memory growth cannot be configured on a PhysicalDevice with virtual devices configured.

For example:

physical_devices = config.experimental.list_physical_devices('GPU')
assert len(physical_devices) > 0, "Not enough GPU hardware devices available"
tf.config.experimental.set_memory_growth(physical_devices[0], True)

Args:

  • device: PhysicalDevice to configure
  • enable: Whether to enable or disable memory growth
