Carla-RSS "Build" process about ad-rss-lib HOT 5 CLOSED

Hi,
no worries. When integrated with CARLA you don't compile ad-rss-lib by doing anything manually from your end within ad-rss-lib. So you don't call colcon yourself, the build system of CARLA is doing that for you. The build commands above from the CARLA documentation refer to the adapted build commands to build CARLA including RSS support. So if you have a look at https://carla.readthedocs.io/en/latest/build_linux/ then you will see that instead of
make package
for integration of RSS with CARLA you just call
make package.rss
Then the build is taking care of downloading ad-rss-lib and integrating it into the CARLA build.

But if you don't want to change anything in the code you might be happy to just download and use the precompiled version with RSS integrated CARLA_0.9.13_RSS.tar.gz from here:
https://github.com/carla-simulator/carla/releases/tag/0.9.13

Then you don't have to compile anything on your own and can just make use of RSS integrated into CARLA.

Thank you very much for your reply. I tried to use the precompiled version RSS directly, but I was executing the command "python examples/rss/manual_ control_ rss.py" in the terminal, the following error occurred:

Then I checked whether the Carla package was installed correctly in the current conda environment, the Carla package has been installed (As shown in the figure below).

In addition, I have also checked whether to import RSS package into Carla according to the tutorial on the official website(As shown in the figure below).This command has been executed.

However, the ad Library in Carla cannot be imported.
Excuse me, what else do I need to check to successfully run RSS in Carla? Thanks in advance.

When compiled together with CARLA, RSS is directly compiled into the CARLA python egg/whl files. It is not using the standalone RSS python library which you can build on your own with ad-rss-lib sources.
Having said that, I would expect that the version of carla python package your conda environment has installed most probably is not the one delivered with the precompiled tarball. Especially the RSS variant is not available via pypi. You have to uninstall the carla python package previously installed via pypi. And then either set the PYTHONPATH variable to the respective egg file, or install the egg or whl file delivered with the tarball under PythonAPI/carla/dist/ directly. See also https://carla.readthedocs.io/en/latest/start_quickstart/#carla-0912
Then the correct interface should be available and the import statement should work fine.

You are using CARLA 0.9.12. Be aware that this bugfix PR carla-simulator/carla#4604 fixing some issues with changed threading behavior of 0.9.12 was integrated in 0.9.13 version. So I would recommend to use 0.9.13 of CARLA.

Thank you very much for your advice, which is very warm for novices.@berndgassmann

I have found the problem, that is, version 0.9.12 Carla needs to be used egg file to enable the carla library. I mistakenly thought that version 0.9.12 belongs to the 0.9.12 + mentioned on the official website (https://carla.readthedocs.io/en/0.9.13/start_quickstart/).

By the way, I'd like to make some suggestions for the official website tutorial (maybe it's just my understanding). When 0.9.12 + is mentioned on the official website, it can be specially noted, that is, 0.9.12 is not included. My advice may be naive, but it would be great if it helped your team.

Thank you again for your patient reply.

It's not because of Carla 0.9.12 that requires the egg file and not the pypi version, it's actually the special RSS built variant that requires to use the egg/whl from the tarball.

Great that it is now working for you.
