Error during launching the Office World about rmf_demos HOT 16 CLOSED

Airdropping my two cents:

The "no namespace found" error caught my eye. I think I have encountered something like that before.
It might be worth a shot removing all traces of ros-gazebo-pkgs (ROS1 and ROS2) and Gazebo,

sudo apt remove ros-[your ROS1 and ROS2 distros]-gazebo-ros-pkgs
sudo apt remove gazebo*

and reinstalling only Gazebo and ROS2 gazebo-ros-pkgs according to the rmf_demos setup:
https://github.com/osrf/rmf_demos#setup

Hopefully this helps?

from rmf_demos.

I have the issue too, it says no namespace found. After updating the office.launch.xml with the following, it solves the namespace issue.

<let name="model_path" value="$(find-pkg-share rmf_demo_maps)/maps/office/models:$(find-pkg-share rmf_demo_assets)/share/rmf_demo_assets/models:/usr/share/gazebo-9/models" />

However, the models of chairs and coke etc. cannot be loaded as shown below:

from rmf_demos.

Found part of the solution here. The office world is loaded successfully. But I haven't check the delivery request.

1. You need to install gazebo manually with version above 9.12.0 http://gazebosim.org/tutorials?cat=install&tut=install_ubuntu&ver=9.0. Following the instructions in this link, and you can install version 9.13.0.
2. Proceed the ROS prerequisites. The command rosdep install in the repo README.md
3. Launch the launch file, and you might get an error
   gazebo: symbol lookup error: /usr/lib/x86_64-linux-gnu/libgazebo_common.so.9:
4. Install the missing package sudo apt upgrade libignition-math2
5. Relaunch your launch file and you may successfully load the office world.

from rmf_demos.

I will make a corresponding PR solving this issue, but if you think that the problem is actually related to the packages with the same namings, just neglect it.

from rmf_demos.

the substitution tag $(find-pkg-share ...) should by default lead to the path ws/install/PACKAGE/share/PACKAGE. I have just finished a new build and have not been able to reproduce your issue.

Could you provide the full gist or log when you launch the world?

from rmf_demos.

Additionally,

$ ros2 pkg prefix rmf_demo_assets
~/rmf_demos_ws/install/rmf_demo_assets
Possibly $(find-pkg-share ...) is not working correctly somehow.

from rmf_demos.

I just did a fresh build again, without any issues, here is my gist.

Is OfficeChairBlack the only model you had issues with? Are you by any chance not on the master branch of rmf_demos? Some models might be missing on certain branches due to active development

from rmf_demos.

@KaeYan does the solution proposed by @cnboonhan94 above solve the problem?

from rmf_demos.

@Yadunund I have tried both following the solution and additionally downloading Gazebo assets beforehand, but the issue similar to @KaeYan still persists.

@aaronchongth , nope, the OfficeChairBlack is not the only model missing, but all objects in rmf_demo_assets package. Yes, I am on master branch

from rmf_demos.

Can you verify that you can find the models in ~/rmf_demos_ws/install/rmf_demo_assets/share/rmf_demo_assets/models? For example OfficeChairBlack would refer to ~/rmf_demos_ws/install/rmf_demo_assets/share/rmf_demo_assets/models/OfficeChairBlack.

also, whenever you attempt a fresh build, please ensure to delete the directories ~/rmf_demos_ws/install, ~/rmf_demos_ws/build, before starting the build again,

cd ~/rmf_demo_ws
rm -rf build install log

source /opt/ros/eloquent/setup.bash
colcon build

colcon will not update or install your new build unless package source files have changed (non-binaries)

Yes, the models are in the folder you mentioned, however, still have errors launching the office.launch.xml

from rmf_demos.

hopefully everything ROS2 Eloquent related is updated?

sudo apt update && sudo apt upgrade

It looks to me like find-pkg-share resolves incorrectly to empty string, giving the FilePath does not exist error. Could this be an outdated ros2/launch? What happens if we replace

$(find-pkg-share rmf_demo_maps)/maps/office/models:$(find-pkg-share rmf_demo_assets)/share/rmf_demo_assets/models

with the corresponding full path of rmf_demo_maps and rmf_demo_assets in the install folder?
For example,

/[your home path]/rmf_demos_ws/install/rmf_demo_maps/share/rmf_demo_maps/maps/office/models:/[your home path]/rmf_demos_ws/install/rmf_demo_assets/share/rmf_demo_assets/models

Or perhaps a clean install of ROS2 ?

from rmf_demos.

Hi, I have been experiencing the same issue of launching the office world. I think there might be some issue with the gazebo version?
Experiencing the same "no namespace found" issue, I noticed that the gzserver crashes after throwing some error, for example:
[gzserver-7] terminate called after throwing an instance of 'std::bad_alloc' [gzserver-7] what(): std::bad_alloc

I noticed that all the crashes occurred in the gazebo version 9.0.0, which is the latest version you can install from apt-get. But I check the log provided by Aaron, and I found he is using gazebo version 9.12.0.

Is there any way that we can upgrade the gazebo version to 9.12.0? I think there may be some bugs in version 9.0.0.

from rmf_demos.

@FloodShao You solution works for me! I guess the README gazebo link needs to be updated. 9.0.0 definitely doesn't work.

from rmf_demos.

Thanks for tracking down this notorious problem @FloodShao. We will update the Setup instructions accordingly.
