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 = tf.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)


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