Issue running OpenVINO 2019.1 classification sample on Arria 10

I am working with an Arria 10 PAC card in a server running RHEL 7.6. I have ensured the firmware on the PAC is up to date (1.2) and am using the fpga_2019.1.133 release of OpenVINO. I followed the steps outlined at https://docs.openvinotoolkit.org/latest/_docs_install_guides_PAC_Configure_2019R1.html and get to the point of attempting to run the classification_sample with the -d HETERO:FPGA,CPU flag. The same script appears to run fine in CPU only mode. Here is the error output.

I can provide the output of the test commands I ran leading up to that error if that helps.
