YOLOV3 warnings

[WU__Tianwen]

hello everyone！

My openvino version is 2020.1. When i run yolov3,some warning happen：

DeprecationWarning: shape property of IENetLayer is deprecated. Please use shape property of DataPtr instead objects returned by in_data or out_data property to access shape of input or output data on corresponding ports
out_blob = out_blob.reshape(net.layers[net.layers[layer_name].parents[0]].shape)

Although it does not affect the operation of the program，but it will print every frame.maybe it will slow the program

What should I do to stop it from warning?

i have tried

import warnings

warnings.filterwarnings('ignore')

but it doesn't work.    should i install openvino2020.3?

ubuntu 16.04
python 3.5.2
openvino 2020.1
CPU intel i5-8250U GPU UHD620
warning will happen on both CPU and GPU

https://docs.openvinotoolkit.org/2020.1/ie_python_api/classie__api_1_1IENetLayer.html the api allso mentioned this warning

https://docs.openvinotoolkit.org/2020.1/ie_python_api/classie__api_1_1DataPtr.html but the api doesn't describe DataPtr 's usage in detail .

I don’t know if DataPtr is used to replace IENetLayerin the latest version of yolov3 OpenVINO

Hi,

The latest version of the OpenVINO Toolkit (2020.3) still uses the out_data property to access DataPtr for all output ports. 

In general, I think printing the warnings after every frame would slow compilation time by a little bit.

Update: As you are in v2020.1, please try changing change line 276 to out_blob = out_blob.reshape(net.layers[net.layers[layer_name].parents[0]].out_data[0].shape) in object_detection_demo_yolov3_async.py script and see if DeprecationWarning persists.

I hope this information is helpful.

Best Regards,

Sahira

Thanks!

This question on github was also initiated by me,and it really works,and YOLO parsing time takes less time!

Thanks for your reply！^-^
