Carla: the question of when i run the client.example.py

[errorJY]

when i run the client.ecample.py.I meet the ImportError :No module named 'google'.It's all:
Traceback (most recent call last): File "/home/error/Carla_0.8.2/PythonClient/carla/transform.py", line 18, in <module> from . import carla_server_pb2 as carla_protocol File "/home/error/Carla_0.8.2/PythonClient/carla/carla_server_pb2.py", line 6, in <module> from google.protobuf import descriptor as _descriptor ImportError: No module named 'google' But i had make the protobuf.when i input it:
$ protoc --version
i will get libprotoc 3.5.1.
so i don't know how to do with it.
Thank you for your care.

Hi @errorJY,

Is it possible that you don't have the dependencies installed in Python3?

sudo pip3 install -r PythonClient/requirements.txt

Which Python version are you using for running client_example.py?

[errorJY]

Hi @nsubiron .
Thank you very much .u just like the god that helped me.
i was using the Python3.5 to run the client_example.py. And i think i deal with it by using your method.
Best wishes to u

Hi @nsubiron
when i installed the dependencies,i think it will more fast:
sudo pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple -r PythonClient/requirements.txt
It's will more fast in China...for the wall. u can write it when u upgrate the doc.
