Object detection using hailo8 and yolo26

I want to use yolo26 for object detection task on rpi5 but can don’t receive found objects. I upgraded previous hailo-apps to latest version

Running detection sample results in error below

cd hailo-apps
source source setup_env.sh
python hailo_apps/python/pipeline_apps/detection/detection.py --hef-path yolo26n

INFO | common.core | All required environment variables loaded successfully.
INFO | common.core | Found HEF in resources: /usr/local/hailo/resources/models/hailo8/yolo26n.hef

NMS score threshold is set, but there is no NMS output in this model.
CHECK_SUCCESS failed with status=6
(GStreamer): CRITICAL: gst_vec_deque_push_tail: assertion ‘array != NULL’ failed

I removed nms-score-threshold and nms-iou-threshold and was able to run pipeline but no objects were returned in callback

What parameters should I pass to yolo26 network to get the objects?

Hi @valery,

The new Yolo26 app is the API version (not Gstreamer pipeline type): hailo-apps/hailo_apps/python/standalone_apps/yolo26 at main · hailo-ai/hailo-apps · GitHub

Please let me know if this works for you.

Thanks,

Hi @Michael

Does it mean that yolo26 is not supported in gstreamer pipeline applications? Does Hailo plan to support it in the future?

Hi,
For now not, however it’s always doable based on the API example to try and create the custom post process for pipeline type.
Thanks,
