I am using openvino(2019.3.379) sample app and it returns error below but -d CPU or -d GPU can work.
benchmark_app –d HDDL –m face-detection-retail-0004.xml -i cam -niter 100
Result:[ ERROR ] _client->loadGraph(_graph, networkName, graphFileContent.data(), graphFileContent.size(), config) failed: HDDL_RESOURCE_BUSY
Could you share the name of the HDDL device that you are using? Additionally, did you complete the additional Installation Steps for the Intel Vision Accelerator Design with Intel Movidius VPUs?
