• Jetson Orin Nano DeveloperKit • Deep Stream: 6.4.0 • JetPack Version: 6.0-b52 • TensorRT Version: 8.6.2.3-1+cuda12.2 • CUDA: 12.2

I am trying to run YOLOV7 on Jetson Orin Nano. I have converted the yolov7_training.pt file into onnx format. Then I updated the “config_infer_primary_yoloV7.txt” with following settings:

[property] gpu-id=0 net-scale-factor=0.0039215697906911373 model-color-format=0 onnx-file=yolov7.onnx model-engine-file=model_b1_gpu0_fp32.engine

[class-attrs-all] nms-iou-threshold=0.45 pre-cluster-threshold=0.25 topk=300

then I upated the ‘deepstream_app_config.txt’ with the following settings:

when i run it using deepstream-app -c deepstream_app_config.txt, it gives me the following error: ailed to build CUDA engine ERROR: Failed to create network using custom network creation function ERROR: Failed to get cuda engine from custom library API 0:08:20.237117120 22787 0xaaaaed823e70 ERROR nvinfer gstnvinfer.cpp:676:gst_nvinfer_logger: NvDsInferContext[UID 2]: Error in NvDsInferContextImpl::buildModel() [UID = 2]: build engine file failed 0:08:20.661601186 22787 0xaaaaed823e70 ERROR nvinfer gstnvinfer.cpp:676:gst_nvinfer_logger: NvDsInferContext[UID 2]: Error in NvDsInferContextImpl::generateBackendContext() [UID = 2]: build backend context failed 0:08:20.661676165 22787 0xaaaaed823e70 ERROR nvinfer gstnvinfer.cpp:676:gst_nvinfer_logger: NvDsInferContext[UID 2]: Error in NvDsInferContextImpl::initialize() [UID = 2]: generate backend failed, check config file settings 0:08:20.662771448 22787 0xaaaaed823e70 WARN nvinfer gstnvinfer.cpp:898:gst_nvinfer_start: error: Failed to create NvDsInferContext instance 0:08:20.662810490 22787 0xaaaaed823e70 WARN nvinfer gstnvinfer.cpp:898:gst_nvinfer_start: error: Config file path: /home/jetson/faizan/yolos/DeepStream-Yolo/config_infer_primary_yoloV7.txt, NvDsInfer Error: NVDSINFER_CONFIG_FAILED ** ERROR: main:716: Failed to set pipeline to PAUSED Quitting nvstreammux: Successfully handled EOS for source_id=0 ERROR from primary_gie: Failed to create NvDsInferContext instance Debug info: /dvs/git/dirty/git-master_linux/deepstream/sdk/src/gst-plugins/gst-nvinfer/gstnvinfer.cpp(898): gst_nvinfer_start (): /GstPipeline:pipeline/GstBin:primary_gie_bin/GstNvInfer:primary_gie: Config file path: /home/jetson/faizan/yolos/DeepStream-Yolo/config_infer_primary_yoloV7.txt, NvDsInfer Error: NVDSINFER_CONFIG_FAILED App run failed

could you suggest what is the problem. I am exactly following the instructions but still getting the error.
