1.2 Python + MultiStick

plugin = IEPlugin(device = "MYRIAD")
plugin.set_config({"KEY_VPU_FORCE_RESET"： "NO"})

↓

plugin = IEPlugin(device = "MYRIAD")
plugin.set_config({"VPU_FORCE_RESET": "NO"})

1.3 Init requests (2 sticks)

self.net = IENetwork.from_ir(model=model_xml, weights=model_bin)
self.exec_net = self.plugin.load(network=self.net, num_requests=2)

1.4 Switch async (2 sticks)

".wait(-1)" is synchronous processing.

self.exec_net.start_async(request_id=self.next_request_id, inputs={input_blob: image})
if self.exec_net.requests[self.current_request_id].wait(-1) == 0:
    res = self.exec_net.requests[self.current_request_id].outputs[out_blob]
    ・・・
# exchange request id
self.current_request_id, self.next_request_id = self.next_request_id, self.current_request_id
