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 = 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)

Args
device	PhysicalDevice to configure
enable	Whether to enable or disable memory growth
