Automatic_control Carla 0.9.3

[lijecaru]

I'm in Ubuntu 16.04 x64 and just downloaded Carla 0.9.3. I want to run the file automatic_control.py but an error appears saying that it couldn't import agents.navigation.roaming_agent. Actually a red line indicating error appears when I also import Carla, but I didn't pay attention to it, since the manual_control.py script works. I wonder if I'm missing something. Thanks.

I have the same error on Ubuntu 18.04

Hello from the pygame community. https://www.pygame.org/contribute.html
Traceback (most recent call last):

But I tried to edit the imports and it worked for me Replace every .agents. with PythonAPI.agents.

I am facing the same issue. For some reasons, @moh3th1 solution did not work for me. But adding 'PythonAPI' to sys.path worked.

Add the below to the code,

try:  
    sys.path.append('PythonAPI')   
except IndexError:  
    pass

I tried both solutions and it didn't work. The solution provided by @moh3th1 gives me also an import error: ImportError: No module named PythonAPI.agents.navigation.roaming_agent

And the solution from @vvrs provides the following output:

Do you maybe have other ideas of what the problem could be? Thank you!

For the problems regarding import error, its best to add the following:

try:
    sys.path.append(glob.glob('PythonAPI')[0])
except IndexError:
    print("PythonAPI package wasn't found")

try:
    sys.path.append(glob.glob('**/agents')[0])
except IndexError:
    print("PythonAPI/agents package wasn't found")

try:
    sys.path.append(glob.glob('**/agents/navigation')[0])
except IndexError:
    print("PythonAPI/agents/navigation package wasn't found")

try:
    sys.path.append(glob.glob('**/agents/tools')[0])
except IndexError:
    print("PythonAPI/agents/tools package wasn't found")

Also make sure that the pip package networkx is installed. However @lijecaru 's problem is completely unrelated to these.

Do you maybe have other ideas of what the problem could be? Thank you! @lijecaru I encountered the same problem > NetworkXNoPath: Node 244 not reachable from 205, have you managed to solve this?

Hi @geekhut , I installed networkx using pip install networkx and then I restarted my PC. After this it worked, hope it helps!

For windows this will help. install package using pip utility as the following

go to directory PythonAPI/carla/agents and create setup.py file and write the following code in that file

from distutils.core import setup
setup(name='agents',
        version='0.9.5', #doesn't matter I guess
        py_modules=['agents'],
        )

Now go to anaconda terminal and do cd to directory PythonAPI/carla and apply following command to install agents

pip install -e agents

This will install agents and resolve the agents.navigation not found issue

It's works for me. try: sys.path.append(os.path.dirname(os.path.dirname(os.path.abspath(__file__))) + '/carla') except IndexError: pass

Hello, I met the same question. I am in ubuntu20.04, and carla version is 0.9.5. I put the carla/agents folder into the examples folder and it makes sense. Hope to help you.
