Apollo: Show rostopic Error

[Triangle001]

Hello.
After using the command "scripts/bootstrap.sh" to launch apollo，I want to see some data about a topic so execute the command "rostopic echo /apollo/localization/pose" , the result shows that:
the rosdep view is empty: call 'sudo rosdep init' and 'rosdep update'
ERROR: Cannot load message class for [pb_msgs/LocalizationEstimate]. Are your messages built?

System information

• OS Platform and Distribution (Linux Ubuntu 14.04):
• Apollo version (3.0):

Can you help me please? Thanks.

1, Did you execute commads(rostopic echo /apollo/localization/pose ) in docker?

1. Inadditional, if you just start Bootstrarp, that will setup monitor and dreamview module, apollo / localization / pose'doesn't have data, you need torosplay`, or configure and start GNSS module.

[Triangle001]

yes , I execute commads(rostopic echo /apollo/localization/pose ) in docker.You suggest me ：
1.into docker
2.start Bootstrap.sh
3.start localization modules
4.rostopic echo /apollo/localization/pose

1. Check whether those class definitions are under /apollo/py_proto
2. Double check your environment variable PYTHONPATH to include the path to the msg class definition.

whether the localization module work well also depends on the gps module , you may need run :
bash roscore.sh start
bash gps.sh start

I also have this problem, how did you solve this problem, thank @Triangle001

Hi, I also got the same question when I want to record all the ros messages. Have you solved the problem?
I have manually started all the related modules. Also, I am pretty sure all the class definations are under /apollo/py_proto and this path has been included to env PYTHONPATH.

Stale issue closed. ROS based Apollo is no longer supported.
