tf.config.get_logical_device_configuration

Get the virtual device configuration for a tf.config.PhysicalDevice.

tf.config.get_logical_device_configuration(
    device
)

Returns the list of tf.config.LogicalDeviceConfiguration objects previously configured by a call to tf.config.set_logical_device_configuration.

For example:

physical_devices = tf.config.list_physical_devices('CPU')
assert len(physical_devices) == 1, "No CPUs found"
configs = tf.config.get_logical_device_configuration(
  physical_devices[0])
try:
  assert configs is None
  tf.config.set_logical_device_configuration(
    physical_devices[0],
    [tf.config.LogicalDeviceConfiguration(),
     tf.config.LogicalDeviceConfiguration()])
  configs = tf.config.get_logical_device_configuration(
    physical_devices[0])
  assert len(configs) == 2
except:
  # Cannot modify virtual devices once initialized.
  pass

device PhysicalDevice to query

List of tf.config.LogicalDeviceConfiguration objects or None if no virtual device configuration has been set for this physical device.
