No module named 'examples.manual_control'

[jbirtel]

Hi,

I just tried to run the test scenario. I first had an issue that the PYTHONPATH for scenario_runner.py was not found. I use openpilot and somehow the PYTHONPATH is set to ...../openpilot and I can't find the file where it is saved (but actually not .profile and not .bashrc), even though I set the PYTHONPATH correctly in bashrc file.

I could somehow solve this by adding the paths with sys.path.append('......') to the python file (scenario_runner.py).

Afterwards, I was able to start scenario_runner and in CARLA, the weather changed. When I now tried to complete the test scenario by starting 'manual_control.py' in the scenario_runner folder, I got the same error, so again I added the paths manually by adding sys.path.append('.....'). This solved the error 'no module name carla'.

However, now I am stuck with the following error:

File "manual_control.py", line 71, in <module> from examples.manual_control import (World, HUD, KeyboardControl, CameraManager, CollisionSensor, LaneInvasionSensor, GnssSensor, IMUSensor) ModuleNotFoundError: No module named 'examples.manual_control' By now, I added the following lines to manual_control.py: (/.../ is on purpose only for this post)

import glob import os import sys sys.path.append('carla/PythonAPI') sys.path.append('/home/..../carla/PythonAPI/carla') sys.path.append('/home/.../carla/PythonAPI/carla/agents') sys.path.append('/home/.../carla/PythonAPI/carla/dist/carla-0.9.11-py3.6-linux-x86_64.egg') sys.path.append('/home/.../carla/PythonAPI/examples')

Can anybody please help me either finding where that PYTHONPATH variable is overwritten and resetting that or by adding another line for sys.path.append()? That'd be great!

The path you want is /home/.../carla/PythonAPI, which is your case, is the only one that doesn't have the home/.../ initial statement. Is this also the case for your manual_control.py file?

[jbirtel]

No, in my manual_control.py this is indeed correct. Sorry, that I put that mistake in the description above. So all paths start with '/home/..../carla/', also that one with PythonAPI. So, I guess this is, unfortunately, not the problem here.

Then I don't know what your problem is. I just removed all PYTHONPATHs related to CARLA and did your sys.path.append(...) and it works fine for me. In any case, I don't think you should follow this route, as there are a lot of file where CARLA is imported and you're going to have to add it to all of them.

Maybe try to add __init__.py file to the carla/PythonAPI/examples folder.

@glopezdiest Hmm, unfortunately it does not work for me, there is still the error. I don't know why, but the PYTHONPATH approach does not work for me. That's why I tried the approach with the sys.append, and I was able to solve the first problem.

@Jk7913 thanks for your help, but this does not change anything (I simply added two empty files with the name init.py in carla/PythonAPI and carla/PythonAPI/examples, was this correct?)

If I run the following command: export PYTHONPATH=$PYTHONPATH:${CARLA_ROOT}PythonAPI:${CARLA_ROOT}PythonAPI/carla:${CARLA_ROOT}PythonAPI/examples:${CARLA_ROOT}PythonAPI/carla/dist/carla-0.9.11-py3.6-linux-x86_64.egg:${CARLA_ROOT}PythonAPI/carla/agents

before the execution of manual_control.py it worked for me. (I left out the '/' after CARLA_ROOT because it is already in my CARLA_ROOT)
