hi ,i use your python code with python 3.7,tensorflow 1.5.4,carla 0.8.2,ubuntu 18.04
but ,i can't run this simulation,
it work error,
INFO:tensorflow:Restoring parameters from models/saveNet_1907.ckpt-158700

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

can you tell me how to deal with this problem？thanks！
or can you tell me your enviroment? thansk!

I guess it's caused by TensorFlow. Can you try using tensorflow 1.12.0? Let me know if it still doesn't work.

yes ,thansk your suggestion very much,
i use python 2.7,carla 0.8.2,tensor flow 1.12.0,can run this code.
