can't install python3.8 carla package on ubuntu 20.04 container

[PinkJohnOfUs]

Problem you have experienced: Not possible to install carla python package for python3.8 on docker container

What you expected to happen: installation should work with: pip install carla

CARLA version: 9.12 Platform/OS: Ubuntu 20.04.3 LTS -> docker container -> ros:foxy-ros-base IMAGE ID: 62ee1d4d17a9
docker run --name ros-bridge-container -it ros:foxy-ros-base /bin/bash

Inside container

$user@ros-bridge-container: lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.3 LTS
Release:        20.04
Codename:       focal

python version:

$user@ros-bridge-container:  python --version
Python 3.8.10
$user@ros-bridge-container: pip --version
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)

Steps to reproduce:

I do not understand why pip tries to download 0.9.5 and not 0.9.12 or 13

$user@ros-bridge-container: pip install carla
Collecting carla

Other information (documentation you consulted, workarounds you tried): I've also downloaded wheel directly and tried:

$user@ros-bridge-container: pip install carla-0.9.12-cp38-cp38-manylinux_2_27_x86_64.whl 
ERROR: carla-0.9.12-cp38-cp38-manylinux_2_27_x86_64.whl is not a supported wheel on this platform.

From host pc (linux ubuntu 20.04) installing carla is no problem:

k@os: pip show carla

Hi @PinkJohnOfUs, You require pip version 20.3 or above to install the CARLA Python package. You can upgrade pip in the following way:

pip install --upgrade pip

If you want to install the python package for CARLA 0.9.12, you should specify the version (currently, the latest version of CARLA is 0.9.13):

pip install carla==0.9.12

Thank you that solved my issue. For all who do have the same problem with ros:foxy-ros-base you should do pip upgrade within dockerfile, it wasn't possible for me to upgrade pip within running container.

I have the same problem. Have you got a solution yet?

I have the same version of ubuntu and python, and the error message. I solved it by this:

sudo apt install python=3.7 sudo gedit ~/.bashrc Add this in the last line: alias python3='/usr/bin/python3.7' source ~/.bashrc Then try pip install carla
