Hello everyone
How can I use the yoloV3 model in deepstream_python_apps,
I have been in “deepstream-app -c deepstream_app_config_yoloV3_tiny.txt” is successful

you can modify the python/apps/deepstream-test1/dstest1_pgie_config.txt to use YoloV3 model , and run with deepstream_test_1.py

This is a log, there is no video window, what is the problem

did you try my steps? If not, can you elabrfate your op steps?

My fault, the yolov3-tiny model ran successfully, thank you,
But yolov3-tiny is not accurate enough, I want to use yolov3,
When I run the yolov3 model, I get a warning “low memory”,
Automatically killed the process

I just tried yolov3 on NANO, it works well.

It is due to the abnormality caused by the video file. I used deepstream-test3 to run mp4 successfully, thanks

Good to know, thanks!

I am trying to get YOLO v3 to run with Python examples’
I need the Python mets data to interface with another program
I am using a mp4 file so I am using the deepstream-test3 example on my Xavier NX
I have done this:
cd /opt/nvidia/deepstream/deepstream-5.0/sources/python/apps/deepstream-test3/
cp …/…/…/objectDetector_Yolo/config_infer_primary_yoloV3.txt dstest3_pgie_config.txt
cp …/…/…/objectDetector_Yolo/yolov.cfg ./
cp …/…/…/objectDetector_Yolo/yolov.weights ./
mkdir nvdsinfer_custom_impl_Yolo
cp …/…/…/objectDetector_Yolo/nvdsinfer_custom_impl_Yolo/libnvdsinfer_custom_impl_Yolo.so ./nvdsinfer_custom_impl_Yolo/
cp …/…/…/objectDetector_Yolo/labels.txt ./
python deepstream_test_1.py …/…/…/…/samples/streams/bird1.mp4

When I run this:
python3 deepstream_test_3.py file:///opt/nvidia/deepstream/deepstream-5.0/samples/streams/bird1.mp4
it runs at 4 fps

When I run this:
deepstream-app -c deepstream_app_config_yoloV3.txt
it runs at 60 fps

How do I modify the :
python3 deepstream_test_3.py
To get it to run at least 30fps

Hi adventuredaisy,

Please help to open a new topic for your issue. Thanks
