笔记本GP76 20.04安装ROS noetic

安装ros noetic

sudo apt-key adv --keyserver ‘hkp://keyserver.ubuntu.com:80’ --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654

利用上述命令添加key（替代了官网的连接）

如果出现下面的问题，修改更新系统选项为全部更新（如果只更新必要的系统Pkg就出现这个问题）
The following packages have unmet dependencies: ros-noetic-desktop-full : Depends: ros-noetic-desktop but it is not going to be installed Depends: ros-noetic-perception but it is not going to be installed Depends: ros-noetic-simulators but it is not going to be installed Depends: ros-noetic-urdf-sim-tutorial but it is not going to be installed E: Unable to correct problems, you have held broken packages.

sudo apt install ros-noetic-desktop-full

安装cuda11.2和cudnn

cuda11.2只能用ubuntu20.04,来用pytorch (安装教程参考OMEN台式机安装)
笔记本rtx3070配合cuda11.2+ubuntu20.04
台式机目前rtx3080 用的pytorch cpu
