Aliases: tf.config.experimental.get_virtual_device_configuration

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

Args:

  • device: PhysicalDevice to query

Returns:

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