在 CPU 上使用推理时,使线程模型与其他应用(以及您使用的任何第三方库)保持一致,以避免过度订购。 自R1 2019 版本以来,OpenVINO™ 工具套件使用英特尔 TBB 预编译,因此任何 OpenMP* API 或环境设置(例如 OMP_NUM_ THREADS)均无效。您可以通过 CPU 配置选项调整特定参数, 例如 CPU 推理使用的线程数。最后,OpenVI...
如果想单线程测试openvino,openvino的多线程的实现使用的是openMP,expor OMP_NUM_THREADS=1。如果想单核测试openvino,我用的方法是,在创建容器时:docker run -it --cpus=1 10.说一下,本人亲测openvino的速度和准确率。我大概使用了80张图片,一共10个类别。大多数类别的识别top-1准确度100%。 我使用的cpu Xen...
