YOLOX with onnxruntime-web

[pconway11]

hello, do you have any examples or tutorials of running YOLOX with onnxruntime-web

I have YOLOX model working successfully, passing in a tensor and getting an output tensor. But I am struggling a bit to convert the output tensor to predictions and bounding boxes

https://github.com/Megvii-BaseDetection/YOLOX/blob/237e943ac64aa32eb32f875faa93ebb18512d41d/yolox/utils/demo_utils.py#L99

Sorry I could not catch your point. Could you say it a bit clear? Anything wrong in demo_postprocess?

[pconway11]

sorry. I am trying to run YOLOX on a web app. So all the code is in javascript. I can use onnx-runtime web to get the output.

but without numpy in javascript I dont fully understand how to process the output to get the predictions.

so I was wondering if there is an example of anyone running YOLOX in a web / javascript.

Sorry we never try such a web application. What a about writing JS code to handle the post processing process and send a PR to this repo? @pconway11

@pconway11 @FateScript Hey have you found any example of usage on the web application? I tried to run this model on this repos:

• https://github.com/Hyuto/yolov8-tfjs
• https://github.com/Hyuto/yolov5-tfjs But unfortunately, it didn't work in any case.

I basically transcribed the python example into javascript. I didn’t find any example on the web.

It mostly worked, but I didn't implement NMS. In many cases in my experiments there was only one bounding box detection in the results so I didn't need NMS.
