Function list_logical_devices

tensorflow/python/framework/config.py:389–414

Return a list of logical devices created by runtime. Logical devices may correspond to physical devices or remote devices in the cluster. Operations and tensors may be placed on these devices by using the `name` of the LogicalDevice. For example: ```python logical_devices = tf.config.

(device_type=None)

@tf_export('config.experimental.list_logical_devices')
def list_logical_devices(device_type=None):
  """Return a list of logical devices created by runtime.

  For example:

  ```python
  logical_devices = tf.config.experimental.list_logical_devices('GPU')
  # Allocate on GPU:0
  with tf.device(logical_devices[0].name):
    one = tf.constant(1)
  # Allocate on GPU:1
  with tf.device(logical_devices[1].name):
    two = tf.constant(2)
  ```

  Args:
    device_type: (optional) Device type to filter by such as "CPU" or "GPU"

  Returns:
    List of LogicalDevice objects
