autowarefoundation / autoware_ai_documentation Goto Github PK

Hi,

I'm reading the autoware.ai document while I install autoware.ai 1.13 from source.

it says (https://github.com/autowarefoundation/autoware_ai_documentation/wiki/Source-Build#system-dependencies-for-ubuntu-1804--melodic):

$ sudo apt install -y python3-pip python3-colcon-common-extensions python3-setuptools python3-vcstool
$ pip3 install -U setuptools

I'm curious that I heard ros melodic only supports python 2 (not python 3), if autoware.ai runs on melodic, what's the point to install python3 for autoware.ai?

Bug report

Images not showing up in quickstart documentation

Screenshots

Additional information

1. Use the official rosbag demo method to load the pdb file on the runtimemanager, showing coding problems, loading to 100%
   
   
2. Using the methods of roslaunch and rviz, the official demo of rosbag only loads the map, but the car does not move, but the data stream of rosbag is always loading, and I do not know how to solve some problems displayed in rviz
   
   Beginners hope to get help from seniors, thank you very much.

Description of the bug

In the autoware rosbag demo /points_map is not produced, consequently most of the demo does not appear to work.

Here another user who encountered this issue: https://answers.ros.org/question/348637/autoware-rosbag-demo-no-points_map/

Steps to reproduce the bug

Follow the demo instructions from here: https://github.com/Autoware-AI/documentation/tree/master/autoware_quickstart_examples
The final step: "Un-pausing the simulation after starting the Map will show the pointcloud map in Rviz." does not work, i.e., rviz does not show the pointcloud (also in the the Quick Start tab of the ARM, there is no "OK" displayed next to the Map launcher file location).

Expected behavior

The node map_file/points_map_loader should correctly load the pcd files from ~/.autoware/data/map/pointcloud_map/, publish appropriately to /points_map, and Rviz should in consequence be able to show the pointcloud map (and other depending autoware features like localization, detection, .. should become functional in the demo).
