Debian CARLA on Ubuntu 20.04 error #3374

Closed shri-can closed 3 years ago

shri-can commented 3 years ago

I'm having a problem with the first step of the Debian CARLA installation in Quick Start Instructions.

It would appear that CARLA's apt repo currently only supports xenial (Ubuntu 16.04) and bionic (Ubuntu 18.04). Have you tried using the package (i.e. extract/run the tar.gz)?

Thanks, but never mind. I realised I needed to build from source so I just downgraded to Ubuntu 18.04. The 20.04 was a fresh install on my dual boot system anyway.

jhermen-List commented 3 years ago

The 18.04 packages work on 20.04 without problems, just do a sudo add-apt-repository "deb [arch=amd64] http://dist.carla.org/carla bionic main"

This worked for me on 20.04.

Esquilli commented 3 years ago

So, the only "fix" is to use 18.04 packages?

togaen commented 3 years ago

@EsquilliDev seems so at the moment. Unfortunately even though the sim runs, the python api doesn't work because the bundled egg file requires python 3.7, but 20.04 ships with 3.8.

Esquilli commented 3 years ago

I was actually able to get it working by doing what was suggested here. I'm also using a conda environment with the right version of Python.

togaen commented 3 years ago

Yeah, I can run a bridge (am using ROS 2), but do any of the util scripts under PythonAPI work for you? They do not work for me. They all give me import errors.

derFrickler commented 3 years ago

It works fine for me on 20.04 if i just add the egg to the path manually before running the scripts: export PYTHONPATH=$PYTHONPATH:/media/fast/LIST/PASCAL/PythonAPI/carla/dist/carla-0.9.10-py3.7-linux-x86_64.egg

togaen commented 3 years ago

@derFrickler Do the util scripts work for you also?

derFrickler commented 3 years ago

Yes, i am pretty sure i used them. And wrote my own scripts based on the examples. you might need to install the following packages as well: apt-get install python3-numpy python3-pygame libxerces-c3.2

togaen commented 3 years ago

I do have those packages. This is what I get when I try to run the config.py script:

$ ./config.py --help
Traceback (most recent call last):
  File "./config.py", line 28, in <module>
    import carla
  File "/opt/carla-simulator/PythonAPI/carla/dist/carla-0.9.10-py3.7-linux-x86_64.egg/carla/__init__.py", line 8, in <module>

ImportError: No module named util

togaen commented 3 years ago

I realized the problem was the shebang in the util scripts... if I change them to invoke the correct python version, everything is fine. In config.py, for example, I just change the top of the file from:

#!/usr/bin/env python

to

#!/usr/bin/env python3

How much effort is it to release a proper Ubuntu 20.04 package? As this is the first step in the Quick start installation, some new users might be irritated?

qhaas commented 3 years ago

In their defense, distro upgrades in enterprise environments isn't pleasant... heck, at my organization, we are still mostly using RHEL7 (contemporary with Ubuntu 14.04) on our production servers to host our headless CARLA runs...

Having support for a new release doesn't mean they can't keep supporting the old versions. It shouldn't require too much effort since most of the problems only require minor version changes.

@joel-mb could you please comment on this?

My question wasn't supposed to be criticism. I never released a package and I can't estimate the required effort. I am very grateful to the whole Carla team.

joel-mb commented 3 years ago

Hi all, I've added the latest CARLA release (0.9.11) in the debian repository for Ubuntu 20.04 (focal).

If you already setup the CARLA debian repository in your system it should work by running:

sudo apt-get update
sudo apt-get install carla-simulator

If you haven't setup the CARLA apt repository just follow the complete process:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 1AF1527DE64CB8D9
sudo add-apt-repository "deb [arch=amd64] http://dist.carla.org/carla $(lsb_release -sc) main"
sudo apt-get update
sudo apt-get install carla-simulator

Please, take into account that, although everything should work well in Ubuntu 20.04, CARLA is only officially supporting Ubuntu 18.04.

amandazhuyilan commented 3 years ago

Note that for users with active firewalls, when setting up the gpg keys in the first step. you might want to do:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 1AF1527DE64CB8D9

instead.

大家好，我已经在 Ubuntu 20.04 （focal）的 debian 存储库中添加了最新的 CARLA 版本（0.9.11）。

如果您已经在系统中设置了 CARLA debian 存储库，它应该通过运行以下命令来工作：
sudo apt-get update
sudo apt-get install carla-simulator
如果您尚未设置 CARLA apt 存储库，请按照完整的过程操作：
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 1AF1527DE64CB8D9
sudo add-apt-repository "deb [arch=amd64] http://dist.carla.org/carla $(lsb_release -sc) main"
sudo apt-get update
sudo apt-get install carla-simulator
请注意，尽管在 Ubuntu 20.04 中一切都应该运行良好，但 CARLA 仅正式支持 Ubuntu 18.04。
