Get the list of visible physical devices.
Returns the list of
PhysicalDevices currently marked as visible to the
runtime. A visible device will have at least one
with it once the runtime is initialized.
The following example verifies all visible GPUs have been disabled:
physical_devices = tf.config.list_physical_devices('GPU')
# Disable all GPUS
visible_devices = tf.config.get_visible_devices()
for device in visible_devices:
assert device.device_type != 'GPU'
# Invalid device or cannot modify virtual devices once initialized.
device_type: (optional string) Only include devices matching this device type. For example "CPU" or "GPU".
