Hi,

The error indicates the OpenBLAS doesn’t build with OpenMP support.
But YOLOv5 source do use OpenMP for acceleration.

To workaround this, you can try to set OMP_NUM_THREADS=1 to turn-off multi-thread.
Or you can re-install OpenBLAS from source by compiling it with USE_OPENMP=1.

Thanks.

Using YOLOv5 on AGX uses the CPU and not the GPU
