tf.config.experimental.set_memory_growth

TensorFlow 2 version View source on GitHub

Set if memory growth should be enabled for a PhysicalDevice.

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
