1 there is an error printing “failed to build network since there is no model file matched.”, seemed to can’t find your model, what is your model format? can you provide your configure file?
2 using nvidia’s yolov4-tiny model, I can’t reproduce your issue in deepstream-test3 , here is the model link:deepstream_reference_apps/download_models.sh at master · NVIDIA-AI-IOT/deepstream_reference_apps · GitHub
3 this error code is in deepstream\deepstream\sources\libs\nvdsinfer\nvdsinfer_model_builder.cpp, it is opensource code, you can add some logs to debug.
