- -![faq_rpc_error](img/faq_rpc_error.jpg) - -If running a script returns an output similar to this, there is a problem with the `.egg` file in the PythonAPI. - -First of all, open `/PythonAPI/carla/dist`. There should be an `.egg` file for the corresponding CARLA and Python version you are using (similar to `carla-0.X.X-pyX.X-linux-x86_64.egg`). Make sure the file matches the Python version you are using. To check your Python version use the following command. - -```sh -python3 --version # CARLA no longer provides support for Python2, so we are dismissing it here -``` - -If either the file is missing or you think it could be corrupted, try rebuilding again. -```sh -make clean -make PythonAPI -make launch -``` -Now try one of the example scripts again. - -```sh -cd PythonAPI/examples -python3 dynamic_weather.py -``` - -If the error persists, the problem is probably related with your PythonPATH. These scripts automatically look for the `.egg` file associated with the build, so maybe there is any other `.egg` file in your PythonPATH interfering with the process. Show the content of the PythonPATH with the following command. - -```sh -echo $PYTHONPATH -``` -Look up in the output for other instances of `.egg` files in a route similar to `PythonAPI/carla/dist`, and get rid of these. They probably belong to other instances of CARLA installations. For example, if you also installed CARLA via *apt-get*, you can remove it with the following command, and the PythonPATH will be cleaned too. -```sh -sudo apt-get purge carla-simulator -``` - -Ultimately there is the option to add the `.egg` file of your build to the PythonPATH using the `~/.bashrc`. This is not the recommended way. It would be better to have a clear PythonPATH and simply add the path to the necessary `.egg` files in the scripts. - -First, open the `~/.bashrc`. -```sh -gedit ~/.bashrc -``` - -Add the following lines to the `~/.bashrc`. These store the path to the build `.egg` file, so that Python can automatically find it.
