tf.config.PhysicalDevice( name, device_type )
TensorFlow can utilize various devices such as the CPU or multiple GPUs for computation. Before initializing a local device for use, the user can customize certain properties of the device such as it's visibility or memory configuration.
Once a visible
tf.config.PhysicalDevice is initialized one or more
tf.config.LogicalDevice objects are created. Use
tf.config.set_visible_devices to configure the visibility of a physical device and
tf.config.set_logical_device_configuration to configure multiple
tf.config.LogicalDevice objects for a
tf.config.PhysicalDevice. This is useful when separation between models is needed or to simulate a multi-device environment.
name: Unique identifier for device.
device_type: String declaring the type of device such as "CPU" or "GPU".
