CL_OUT_OF_HOST_MEMORY error when running in HETERO mode (-d HETERO: FPGA, CPU).

Hardware/Software Used

Intel® Distribution of OpenVINO™ Toolkit 2018 R5

Intel® Vision Accelerator Design with Intel® Arria® 10 FPGA (IEI's Mustang-F100-A10)

Run pedestrian demo will mall.mp4 video following video tutorial (https://www.youtube.com/watch?v=OKH57mvO9k0),

but got errors.

Takeaways:

Seems to run on CPU, will not run on FPGA due to “OUT OF HOST MEMORY” error, shown below.

Questions/Concerns:

· Not really sure what the performance metric would be on this kind of demo / I don’t know where to output an FPS or other metric

o Copy from face detection to get fps on pedestrian tracker

· Works on CPU, does not run on HETERO:FPGA,CPU (error screenshot below)

Trying Different Bitstreams

· MobileNet / SqueezeNet / Generic / AlexNet_GoogleNet / ResNet / TinyYolo_SSD300 / VGG error

· ELU / RMNet error

o Video pops up briefly then goes away, doesn’t show tracking mechanism
