我想在GPU中运行我的代码。
我有两个OpenCV版本：
cv_bridge ....................................... ......仅在CPU中cv_bridge ........>在运行代码时，系统会考虑ros-kinetic-opencv3 default。因此，我通过以下方式删除了ros-kinetic-opencv3：sudo apt remove ros-kinetic-opencv3，我使用this这样的GPU增强功能为OpenCV构建了cv_bridge（我在catkin_ws / src中下载vision_opencv，然后使用catkin_make和source ./devel/setup.bash）
我尝试运行两台相机：
1）相机名称：ASUS xtion
当我运行相机时：roslaunch openni_launch openni.launch，出现此错误[openni.launch] is neither a launch file in package [openni_launch] nor is [openni_launch] a launch file name The traceback for the exception was written to the log file。
[使用此命令时：sudo apt-get install ros-kinetic-openni-launch，它可以工作但是用CPU而不是GPU运行，为什么？由于已安装ros-kinetic-opencv3，因此我需要使用第一步（删除ros-kinetic-opencv3），这意味着一个封闭的循环
[2）摄像机名称：Orbbec Astra
我做了ASUS xtion之类的第一步和第二步。当我运行相机时：roslaunch astra_camera astra.launch出现此错误：

sudo apt install ros-kinetic-rgbd-launch修复了此错误，但是可以用CPU而不是GPU运行为什么？由于已安装ros-kinetic-opencv3，因此我需要使用第一步（删除ros-kinetic-opencv3），这意味着一个封闭的循环
请帮助我或有任何建议吗？
