Yolov5: ERROR: Failed to get cuda engine from custom library API

[flmello]

• Hardware Platform (Jetson / GPU) Jetson nano Devkit • DeepStream Version 6.0.0 • JetPack Version (valid for Jetson only) 4.6 • TensorRT Version 8.2.1.8

I have an script running on Jetson Xavier AGX, DS 6.3.0, JetPack 5.1, TensorRT 8.5.2.2. But when I tranfer this script to a nano devkit (specs above) I got error during the ONNX model conversion:

Note that I had success in compiling nvdsinfer_custom_impl_Yolo with the correct Cuda version: CUDA_VER=10.2 make -C nvdsinfer_custom_impl_Yolo

The libnvdsinfer_custom_impl_Yolo.so path is correct in my config file dstest4_pgie_nvinfer_yolov5_config.txt.

There is something tricky here, but I couldn't find out. Does anyone can give me a tip of what is going on?
