anaconda - 尽管指定使用 GPU，YOLO 仍继续使用 CPU

Question

我正在使用带有 GPU 0：Intel(R) HD Graphics 630 和 GPU 1：GTX1050 TI 的笔记本电脑。我刚刚使用以下教程在 Anaconda 环境中设置了 YOLO 环境：https ://appliedmachinelearning.blog/2018/05/27/running-yolo-v2-for-real-time-object-detection-on-videos-images -通过-暗流/

问题是：每当我尝试使用 GPU 在 Anaconda 环境中使用 YOLO 渲染视频时

python flow --model cfg/yolo.cfg --load bin/yolov2.weights --demo videofile.mp4 --saveVideo --gpu 0.5

视频确实渲染成功，但是，我的 CPU 使用率几乎上升到 100%（任务管理器），而我的 GPU 根本没有使用。我尝试通过在末尾添加 --gpuName /gpu:1 来指定 GPU 名称，但仍然使用 CPU。这是从 Anaconda Prompt 复制的输出行。

然后，如果我尝试改为渲染图像，任务管理器仍然显示根本没有使用 GPU。

怎么了>_<？？？提前致谢！

您是否对 Makefile 进行了一些更改，在 Makefile 中启用 GPU 和 CUDNN。小心路径。
