openpose 编译告诉 libopenpose.so：对 `op::renderPartAffinityFieldGpu(...t)' 的未定义引用

Question

我的配置是：

Openpose:latest(2017-05-29) master branch
Caffe   :latest(2017-05-29) master branch
OpenCV  :3.1
Ubuntu  16.04 64bit
GCC     :5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4)

我想在我的带有 AMD 视频卡的笔记本电脑上尝试 openpose，所以我禁用了 CUDA，并在 caffe Makefile.config 中启用了 opencv 3，如下所示：

CPU_ONLY := 1
OPENCV_VERSION := 3

编译caffe后，

cp openpose/3rdparty/caffe/Makefile.config openpose/

然后

make all -j 10

得到这些：

示例代码似乎仍然使用 cuda/gpu 相关的东西，是吗？如何解决这个问题？

Answer 1

抱歉，您不能为 OpenPose 禁用 GPU（也不能禁用 OpenPose 将使用的 Caffe）。

OpenPose的CPU代码没有写完（速度很慢，暂时估计写不完）。您将不得不使用 CUDA + cuDNN。因此，一台带有NVIDIA显卡的机器。
