Ubuntu-Sim2Real环境配置（下）

cd ICRA-RM-Sim2Real/docker_client/
./exec_client.sh
cd ~
roslaunch rtab_navigation rtab_navigation.launch

执行上面代码的时候后台一直刷新

cd ICRA-RM-Sim2Real/docker_client/
./exec_client.sh
cd ~
roslaunch carto_navigation navigation.launch

?1.Usage

执行该代码的时候出现了下面的问题

使用下面代码打开bashrc文件

nano ~/.bashrc

将最后的下面的代码

# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
if ! shopt -oq posix; then
  if [ -f /usr/share/bash-completion/bash_completion ]; then
    . /usr/share/bash-completion/bash_completion
  elif [ -f /etc/bash_completion ]; then
    . /etc/bash_completion
  fi
fi

# >>> fishros initialize >>>
 source /opt/ros/noetic/setup.bash 
# <<< fishros initialize <<<

# >>> fishros scripts >>>
export PATH=$PATH:/home/see/.fishros/bin/ 
# <<< fishros scripts <<<

改为

# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
if ! shopt -oq posix; then
  if [ -f /usr/share/bash-completion/bash_completion ]; then
    . /usr/share/bash-completion/bash_completion
  elif [ -f /etc/bash_completion ]; then
    . /etc/bash_completion
  fi
fi
source /opt/ros/kinetic/setup.bash
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:/home/sz/catkin_ws/src
export ROS_HOSTNAME=localhost
export ROS_MASTER_URI=http://localhost:11311
#source ~/racecar/devel/setup.bash

不过当我重新跑代码的时候，变成了这样，我的rviz黑屏了

副了,所以我把前面的一步撤回，查看

参考下面的博客，但是学长劝我别删除,所以我没管

?Ubuntu虚拟机删除dev/loop_sudo apt autoremove --purge snapd-CSDN博客

配置下面代码的时候

cd ICRA-RM-Sim2Real/docker_client/
./exec_client.sh
roscd ep_detect_and_grasp
python3 detect_cube.py

出现了这个问题

(frame:406): Gdk-ERROR **: 05:10:35.111: The program 'frame' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAccess (attempt to access private resource denied)'.
  (Details: serial 295 error_code 10 request_code 130 (MIT-SHM) minor_code 1)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
Trace/breakpoint trap (core dumped)

不过在我重复三次执行后，它可以调出frame画面，就是好像和指导书的不太一样就是了，无法操控它

运行下面代码的时候

cd ICRA-RM-Sim2Real/docker_client/
./exec_client.sh
roscd ep_detect_and_grasp
python3 grasp_cube.py

出现了这个问题

The publisher should be created with an explicit keyword argument 'queue_size'.

根据提示输入下面代码 注意括号前面有反斜杠 '\'

self.base_move_position_pub = rospy.Publisher\("cmd_position", Twist\)

出现下面的问题：

bash: self.base_move_position_pub: command not found

再次运行下面的代码的时候

cd ICRA-RM-Sim2Real/docker_client/
./exec_client.sh
roscd ep_detect_and_grasp
python3 grasp_cube.py

虽然能出现一个frame窗口，但是有下面的信息提示：
