I’m trying to run the Yolov2 demo on a AWS F1 instance (FPGA DEV AMI version 1.4.0), but get the following error when running ./run.sh aws e2e.

I see that this issue is similar to https://github.com/Xilinx/ml-suite/issues/20. The solution mentioned therein is to ensure that sdaccel_setup.sh is sourced successfully. In my case the following are the last few output lines when sdaccel_setup.sh is sourced:

I also see that the sdaccel_setup.sh script sets XILINX_OPENCL to /opt/Xilinx/SDx/2017.4.rte.dyn, However, on the ml-suite README.md, it is recommended to run the script ml-suite/overlaybins/setup.sh, which sets the same variable back to /home/centos/ml-suite/overlaybins/aws. Could this be a potential mismatch issue, that is leading to the error?
Any pointers on how to resolve this error would be appreciated.
Thanks, Shiril
