Error in rostest ros_bridge_client.test

Hi,
you need to ensure that Python finds the CARLA PythonAPI.
Please see my answer in #14

I am trying to use rosbridge with carla 0.9.2. I am having following error with rostest but unable to figure out the reason. There are lots of warning for traffic light actor and then timeout.
I tested my PythonAPI is working properly.

[WARN] [1545906583.770877, 0.000000]: Created Traffic-Light Actor(id=37, parent_id=0, type=traffic.traffic_light, attributes={}). Not yet fully implemented!

I found the solution I did not read the documentation carefully. We have to run the python script manual_control.py. There was no actor spawned so no datastream so the test was showing timeout.

Ok. Thx for your PR. I just merged it. I will close this issue, as well.

but still ros bridge is not connecting. any help?

@jaypee92 Please follow the instructions. E.g. extend your python path:
export PYTHONPATH=$PYTHONPATH:<path/to/carla/>/PythonAPI/<your_egg_file>

[EvgKlin]

@fpasch Can you please help me. I am running Carla on windows 10 and running the ros-bridge on a Ubuntu virtual machine. I set the shared folder for the VM, so PYTHONPATH will have the egg file from the shared carla folder of the host machine.
When I tried to start the launch file, I got the error. How can I fix this?
