Carla: Crash when runing client_example.py on windows

[imran514]

I am trying to run carla simulator in client-server mode and when i run the python client, i get below crash.

C:\Carla\_CARLA_0.8.4\0.8.4\PythonClient>python client_example.py
INFO: listening to server localhost:2000
CarlaClient connected
Starting new episode at 'Town01'...
Traceback (most recent call last):
  File "C:\Carla\_CARLA_0.8.4\0.8.4\PythonClient\carla\client.py", line 174, in _read_sensor_data
    raise StopIteration
StopIteration

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "client_example.py", line 248, in <module>

Hello @imran514.
Did you modified the client?

[imran5144]

@marcgpuig no i didn't modify the code

[marcgpuig]

@imran5144,
Right now we support Python 2.7, 3.5 and 3.6.
It looks like you are using Python 3.7 and we didn't know this change on 3.7 version.

Thanks for your feedback! We'll keep this in mind.

Thank you @marcgpuig , it works on 3.6.

Did you close this issue, because it has been resolved? I just wanted to open a Pull Request, but couldn't manage to finde client.py.

If you have the problem on the stable version, simply replace raise StopIteration with return.
