OpenVINO 2020.4 monitors

[WU__Tianwen]

2020.4 YOLO demo uses OpenVINO monitors,but how could i use it

monitors.py

try:
    from monitors_extension import Presenter
except ImportError:
    import logging


    class Presenter:
        def __init__(self, keys, yPos=20, graphSize=(150, 60), historySize=20):
            self.yPos = yPos
            self.graphSize = graphSize
            self.graphPadding = 0
            if keys:
                logging.warning("monitors_extension wasn't found")

        def handleKey(self, key): pass

        def drawGraphs(self, frame): pass

        def reportMeans(self): return ''

 these functions are all empty?

args.add_argument('-u', '--utilization_monitors', default='', type=str,
 help='Optional. List of monitors to show initially.')

 whatever the input,the output always "monitors_extension wasn't found" ?

How could i use monitors correctly or it's not finished yet？

Greetings,

1.May I know whether this script is from our official OpenVino documentation?

2.Is this where you are referring to?: https://github.com/TNTWEN/OpenVINO-YOLOV4

3.I checked the whole openvino folders but I could only found monitors.cpp instead of monitors.py, probably you could try out this monitors.cpp.

Sincerely,

Iffa

Hello！

Openvino2020R4 yolov3 python demo use monitors.

https://github.com/TNTWEN/OpenVINO-YOLOV4  this is my project ,and in this issue https://github.com/TNTWEN/OpenVINO-YOLOV4/issues/1 we talked about monitors.

for windows OpenVINO (install in the default path) , python monitor files  path：

C:\Program Files (x86)\IntelSWTools\openvino_2020.4.287\deployment_tools\inference_engine\demos\python_demos\common

Add these files to the project and demo will not report errors

but this .py file  doesn't seem to implement any function

        def handleKey(self, key): pass

        def drawGraphs(self, frame): pass

        def reportMeans(self): return ''

 I also found cpp monitors files,

C:\Program Files (x86)\IntelSWTools\openvino_2020.4.287\deployment_tools\open_model_zoo\demos\common\monitors

But it seems that it can't be used directly in Python demo

Thanks！

Hi @WU__Tianwen 

Utilization monitors feature thru -u parameter is not yet implemented for Object Detection YOLO Python Demo. Be default there is empty value "" provided, and in case of non-empty value provided it just throws the exception message via monitors.py.

You can take a look at the example on how this is implemented in Classification C++ Demo.
With "-u CMD" you can have all 3 utilization monitors being enabled for CPU, all the cores, and memory.
