View source on GitHub

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

Returns:

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