Problem with `face-detection-retail-0004` with openvino_2020.1.023

See original GitHub issue

I would like to use the latest OpenVino, but I have a problem running the face-detection-retail-0004 example. I’m following this tutorial and using this script. I can see the video capture from the camera and the script doesn’t report errors, but the inference does’t work. When I print out print(str(e['label']) + " " + str(e['conf'])) I get constant values:

1.0 0.04296875
1.0 0.04296875
1.0 0.04296875
1.0 0.04296875
1.0 0.04296875
.
.
.

Can I somehow debug further, or should I just switch to the older OpenVINO release?

So @mariusz-r ,

Here’s what I did to quickly get the face detection running.

Also, I didn’t checkout any special branch, just master, and then modified depthai.py, this line:

Changed this to: /home/pi/Desktop/depthai-python-extras/resources/nn/object_detection_4shave/face-detection-retail-0004.blob

As below:

Notice I didn’t change the path to where the class names are, so it says ‘aeroplane’ over my face instead of ‘face’. You can change that as you desire. The first class in the path that I left it pointed to is ‘aeroplane’. If you change this path (or just change the class in the existing file) than you can properly get the face display.

Sorry about the messy examples. We need to clean them up. Will do so this week.

Thanks, Brandon

So @mariusz-r I just updated the OpenVINO face-detection post w/ current use of DepthAI.

https://docs.luxonis.com/tutorials/openvino_model_zoo_pretrained_model/

We’ll probably be updating a bit more as we go forward, specifically to not have to select the neural .blob, the labels .txt, and the tensor format .json all independently. We’re going to move the labels into the .json and have the .blob and the .json live in their own folders so you can just select the folder and the .blob and the .json (which now includes the labels) are used together.

@szabi-luxonis is implementing this change now.

Also closing this issue now but feel free to re-open it if there’s anything more on this.
