我正在尝试让 OpenVINO 样本在 mPCIe Myriad X 卡（带有 2 个 MA2485 芯片）上工作。
我的目标是让样本使用 HDDL 插件工作，据我了解，它应该允许并行处理多个芯片。
使用“MYRIAD”插件，基准测试每次都能成功运行：
sudo -E ./demo_squeezenet_download_convert_run.sh -d MYRIAD
但是，当切换到-d HDDL我得到以下信息：
Run ./classification_sample -d HDDL -i /opt/intel/openvino_2019.1.144/deployment_tools/demo/car.png -m /home/vino/openvino_models/ir/FP16//classification/squeezenet/1.1/caffe/squeezenet1.1.xml

我试过弄乱各种配置选项，但无济于事。我也尝试过重新安装 Ubuntu，但也没有用。
使用 Ubuntu 16.04.6，内核 4.4.0-148-generic。
