一、重装系统

Ubuntu U盘启动工具Rufus制作(详细步骤)
重装了一下，第一次插U盘时死机了？第二次插U盘时正常，好的顺利安装好了ubuntu。安装时直接选的英文，而后需要重新设置language support，有点麻烦，还不如开始的时候就选择中文…

二、参考内容

gym-gazebo要求：
ROS Melodic: Desktop-Full Install recommended, includes Gazebo 9.0.0
Gazebo 9.0.0

1、天涯0508

三、需要安装

tensorflow可以参考‘天涯0508’安装‘tensorflow_gpu-1.8.0-cp27-none-linux_x86_64.whl’

20190419_NVIDIA 驱动版本 cuDNN CUDA Tensorflow四者之间的版本的对应问题：

四、安装应用

把以前下载的各种包直接导进去，然后安装。
安装anaconda3-5.1.0，20180911_Ubuntu16 安装Anaconda3
安装ROS melodic，20190726_Ubuntu18.04安装ROS melodic

melodic昨天没装完今天继续，开机时失败了、像是死机…平时开机也不快，完全不像笔记本上面的ubuntu16.04，快的很。
碰到了昨天同样的问题：

$ sudo rosdep init
ERROR: cannot download default sources list from:
https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list
Website may be down.

卸载 Ubuntu 16.04 Kinetic版本ROS
卸载之后再重装，遭遇了一堆源的问题，最后靠阿里的源救回一命。
另外添加了ROS官方的软件镜像源和中科大的源：

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'

sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.ustc.edu.cn/ros/ubuntu/ $DISTRIB_CODENAME main" > /etc/apt/sources.list.d/ros-latest.list'

再次安装后，出现了更多问题：

(py27) fyo@fyo:~$ sudo rosdep init
Wrote /etc/ros/rosdep/sources.list.d/20-default.list
Recommended: please run

rosdep update

(py27) fyo@fyo:~$ sudo rosdep update

melodic对我确实不太友好…在转战kinetic之前，我还想再试一遍，不过这次直接拿笔记本上的源来安装melodic，看看效果会不会好一点：

且不说能不能安装好，简直快得一笔…有点开心…

# 第一个终端
roscore

# 第二个终端
rosrun turtlesim turtlesim_node

# 第三个终端
rosrun turtlesim turtle_teleop_key

终于又看见熟悉的龟龟了！
所以这两天碰见的麻烦事，主要都是源的问题！

编译其他还好，可是编译uuv包“uuv_simulator”的时候“惊喜”不断，单独发个贴好了，难度有点大、内容应该会很长。

sudo gedit /etc/apt/sources.list

明天打算重装ubuntu16，搭配kinetic！
