Hi, check this issue please https://github.com/carla-simulator/carla/issues/6116

I had encountered a similar issue and I found out that I need to upgrade my CARLA client library to match the version of CARLA server downloaded from GitHub Releases.

Be sure to upgrade the CARLA Python client library by using one of these options (excerpt from official docs):

1. CARLA provides .whl files for different Python versions. You will need to install the .whl file. The .whl file is found in PythonAPI/carla/dist/. There is one file per supported Python version, indicated by the file name (e.g., carla-0.9.12-**cp36**-cp36m-manylinux_2_27_x86_64.whl indicates Python 3.6).

 # Python 3
 pip3 install <wheel-file-name>.whl

 # Python 2
 pip install <wheel-file-name>.whl

If you previously installed the client library, you should uninstall the old one before installing the new one.

2. The CARLA client library can be downloaded from PyPi. This library is compatible with Python versions 2.7, 3.6, 3.7, and 3.8. To install it you will need pip/pip3 version 20.3 or above. See the Before you begin section for how to check the version and upgrade pip/pip3.

It is recommended to install the CARLA client library in a virtual environment to avoid conflicts when working with multiple versions.

To install the client library from PyPi, run the following command:

 # Python 3
 pip3 install carla

 # Python 2
 pip install carla

The PyPi download is suitable for use with CARLA packages only (i.e., not with a version built from source). Since the PyPi download only contains the client library, it is most useful in situations where you will be communicating with a remote CARLA server where you do not require downloading a full CARLA package.

Hope it helps!

Thanks to share!

In fact, my issue was related with the python version that I had on my conda environment. The Python installed was 3.9 instead 3.8. The solution was creating a new environment with python 3.8 and install the .whl located in PythonAPI/carla/dist/ After that client examples runs without any issue.
