Error found when run the code

[lmw0320]

I just followed the steps of commands show in Readme：

1. apt install git-lfs
   git lfs install --skip-repo
   git clone https://github.com/NVIDIA-AI-IOT/deepstream_parallel_inference_app.git
2. apt-get install -y libjson-glib-dev libgstrtspserver-1.0-dev
3. cd tritonserver/
   ./build_engine.sh
   4.cd tritonclient/sample/
   source build.sh
   ./apps/deepstream-parallel-infer/deepstream-parallel-infer -c configs/apps/bodypose_yolo_lpr/source4_1080p_dec_parallel_infer.yml

I can run all the commands sucessfully except the last line, the errors are shown below:

I found that this error was related to "nvinferserver(Triton)".
When I replaced it with "nvinfer(TRT)" stuffs in config file, sucessfully worked.

1. I simply use "bodypose_yolo/source4_1080p_dec_parallel_infer.yml" instead of "bodypose_yolo_lpr/source4_1080p_dec_parallel_infer.yml". because I couldn't find trt engine of lpr.
2. set "plugin-type=0" in primay-gie0 and primay-gie1 of source4_1080p_dec_parallel_infer.yml.
3. change config path to "config_yolov4_infer.txt" and "config_body2_infer.txt".

After that I suddenly met typo erros like "lable.txt doesnt exists". I fixed it. And it works.
(yolov4/lables.txt didn't exisit in proper folder, I copied and renamed as "labels.txt" from coco.names in same directory".

If you want to use "nvinferserver(Triton)", other guys probably help us.

Thanks for your reply. I had tried your advice but still got error as follows:

@lmw0320
"Failed to create infer_bin_muxer" is related to "nvdsmetamux".
"gst-nvdsmetamux" plugin newly introduced in DeepStream 6.1.1 or above.

Check this:

• Your deepstream version is 6.1.1 or above.

Thanks for your reply. I run the code under DP6.1.1， and found new error ;ERROR: infer_trtis_server.cpp:1052 Triton: failed to load model yolov4, triton_err_str:Invalid argument, err_msg:load failed for model 'yolov4': version 1: Unavailable: unable to find '/opt/nvidia/deepstream/deepstream-6.1/sources/apps/sample_apps/deepstream_parallel_inference_app/tritonserver/models/yolov4/1/yolov4_-1_3_416_416_dynamic.onnx_b32_gpu0.engine' for model instance 'yolov4_0';

Have you solved this problem? I have the same problem

Did you install plugin nvinferserver?
