Class Attributes

device

A name of the device that was specified to initialize IEPlugin.

version

A version of the plugin.

Detailed Description

This class is the main plugin interface and serves to initialize and configure the plugin.

Constructor & Destructor Documentation

__init__()

def ie_api.IEPlugin.__init__	(		self,
			device,
			plugin_dirs = None
	)

Class constructor.

Parameters

device	Target device name. Supported devices: CPU, GPU, FPGA, MYRIAD, HETERO, MULTI
plugin_dirs	List of paths to plugin directories

Returns

IEPlugin instance

Member Function Documentation

add_cpu_extension()

def ie_api.IEPlugin.add_cpu_extension	(		self,
			str,
			extension_path,
			except
	)

Loads extensions library to the plugin.

Applicable only for a CPU device and a HETERO device with CPU

Parameters

extension_path

A full path to CPU extensions library

Returns

None

load()

def ie_api.IEPlugin.load	(		self,
			IENetwork,
			network,
			int,
			num_requests = 1,
			config = None
	)

Loads a network that was read from the IR to the plugin and creates an executable network from a network object.

You can create as many networks as you need and use them simultaneously (up to the limitation of the hardware resources).

Parameters

network	A valid IENetwork instance
num_requests	A positive integer value of infer requests to be created. Number of infer requests may be limited by device capabilities.
config	A dictionary of plugin configuration keys and their values

Returns

Valid instance of ExecutableNetwork class

Usage example:

net = IENetwork(model=path_to_xml_file, weights=path_to_bin_file)
plugin = IEPlugin(device="CPU")
exec_net = plugin.load(network=net, num_requsts=2)

set_config()

def ie_api.IEPlugin.set_config	(		self,
			config
	)

Sets a configuration for the plugin.

Refer to SetConfig() in Inference Engine C++ documentation for acceptable keys and values list.

Parameters

config

A dictionary of keys and values of acceptable configuration parameters

Returns

None

set_initial_affinity()

def ie_api.IEPlugin.set_initial_affinity	(		self,
			IENetwork,
			net,
			except
	)

Sets initial affinity for model layers according to the HETERO plugin logic.

Applicable only if IEPlugin was initialized for a HETERO device.

Parameters

net	A valid instance of IENetwork

Returns

None

Usage example: See affinity attribute of the IENetLayer class.
