目前我正在尝试在安装了摄像头的 RPi 零上运行暗流。
使用暗流检测有点慢，但在 pi 3 上运行良好。（虽然编译 opencv3 需要几个小时）所以我认为它在 pi 零上很相似，但事实并非如此。
我设法安装了 opencv 3.3.1（花了一天时间来构建）和 tensorflow（使用
tensorflow-1.4.0-cp35-none-any.whl 从 tensorflow-1.4.0-cp34-none-any.whl 重命名），并且他们工作正常（有点......由于python版本不兼容，tensorflow显示了一些警告 - 但根据Pete Warden的博客它无论如何都可以工作：https ://petewarden.com/2017/08/20/cross-compiling-tensorflow-为树莓派）
用
python setup.py build_ext --inplace
没有任何问题。（它实际上是 python3，因为我在 venv 和 python3 上）
但是当我尝试检查检测是否适用于以下命令时：
./flow --imgdir=sample_img --model cfg/tiny-yolo-voc.cfg --load bin/tiny-yolo-voc.weights --gpu 0
它给出了错误：

我不知道出了什么问题以及如何解决这个问题。你能帮忙吗？
