Error in expected data structure Python Streaming code

[mgreiner79]

in this code here
https://github.com/hailo-ai/Hailo-Application-Code-Examples/blob/main/runtime/python/streaming/yolox_stream_inference.py

on line 67 there is this statement
layer_from_shape: dict = {infer_results[key].shape:key for key in infer_results.keys()}
This throws an error because the data type of infer_results[key] is a list (not a numpy array).

Actually, I dont get what this is supposed to do.
It is going to return a dictionary where they keys are the tensor shape, and the values are the model name (in this case "yolox_s_leaky/yolox_nms_postprocess"). It iterates over all the keys, but there is only one key in infer_results

Given that there is only one key in infer_results, I dont see how the code

endnodes = [infer_results[layer_from_shape[1, 80, 80, 4]],  # stride 8 
                    infer_results[layer_from_shape[1, 80, 80, 1]],  # stride 8 ...

is supposed to work.

Maybe the .hef file has been changes since this code was written (???). I am using the .hef file specified in the get_resource.sh file
("https://hailo-model-zoo.s3.eu-west-2.amazonaws.com/ModelZoo/Compiled/v2.6.1/yolox_s_leaky.hef")
@nina-vilela : Do you have any idea what's wrong here?

Hi @mgreiner79,

As written in the example's README, this code is only guaranteed to work on HailoRT v4.16.0. If you are using a newer HailoRT version, this may explain the issue, as we've had many changes since that HailoRT version.

Thanks @nina-vilela ,
Are there any up-to-date examples published, that you can direct me to?

@mgreiner79 you can take our object detection example and alter it to work with a video input using opencv
