OP is supported, but tensor type isn't matched!

Namaste,

I am not able to run the detection on GPU of RB5 processor. When I am running the detector (I am using a video file as input), I am getting following message:

sh-5.0# ./object-detector 0 ../test_for_rb5.mp4

Thanks in advance for any pointers.
