    Hi,

        The libvx_tidl_rt.so version you are looking at is built for Arm A72.

        For host emulation, you need to the version built for x86.  It should be in the "ti_dl/rt/out/PC/x86_64/LINUX/release/".  Point environment variable LD_LIBRARY_PATH to this directory, so that the inference can find this shared library.
