tf.config.experimental.get_visible_devices( device_type=None )
Returns a list of PhysicalDevice objects that are current marked as visible to the runtime. Any visible devices will have LogicalDevices assigned to them once the runtime is initialized.
The following example verifies all visible GPUs have been disabled:
physical_devices = config.experimental.list_physical_devices('GPU') assert len(physical_devices) > 0, "Not enough GPU hardware devices available" # Disable all GPUS tf.config.experimental.set_visible_devices(, 'GPU') visible_devices = tf.config.experimental.get_visible_devices() for device in visible_devices: assert device.device_type != 'GPU'
device_type: (optional) Device types to limit query to.
