Creating parse-bbox

Robotics & Edge Computing Jetson Systems Jetson Nano

Hello,

I’m new to using the Nvidia Jetson Nano and DeepStream 5.1.

I want to use an onnx model developed by colleague using the “deepstream-test1-usbcam” Python example.

We have been using this model using detectNet but now want to switch to DeepStream:
net = jetson.inference.detectNet(argv=[‘–model=/home/’+currentUser+‘/jetson-inference/python/training/detection/ssd/models/’+folderName+‘/ssd-mobilenet.onnx’, ‘–labels=/home/’+currentUser+‘/jetson-inference/python/training/detection/ssd/models/’+folderName+‘/labels.txt’, ‘–input-blob=input_0’, ‘–output-cvg=scores’, ‘–output-bbox=boxes’, ‘–threshold=0.20’])

I am having trouble making the appropriate changes to the pgie configuration .txt file in the “deepstream-test1-usbcam” example… specifically on making/selecting a parse bbox file.
(The sample code is based on reading a caffemodel model and engine.)

Error:

0:00:05.089327290 14198     0x3b39b320 ERROR                nvinfer gstnvinfer.cpp:613:gst_nvinfer_logger:<primary-inference> NvDsInferContext[UID 1]: Error in NvDsInferContextImpl::fillDetectionOutput() <nvdsinfer_context_impl_output_parsing.cpp:724> [UID = 1]: Failed to parse bboxes using custom parse function

Is there a general config file that you can recommend?

Or are there instructions on how to make the config file for onnx?

Hi,
This looks like a Jetson issue. We recommend you to raise it to the respective platform from the below link

Thanks!

Hi,

We have implemented an example for jetson-inference model with Deepstream in C++ interface below:
https://elinux.org/index.php?title=Jetson/L4T/TRT_Customized_Example#Custom_Parser_for_SSD-MobileNet_Trained_by_Jetson-inference

Could you give it a check first?
Thanks.

Hello,

I got the custom parser you linked above, but I am still getting this error.

I am using an SSD-MobileNet model.

From the config file, can you see if I am doing something wrong?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Hi,

We want to check this in our environment.
Could you share the model and the corresponding configure with us?

Thanks.
