I changed some of you code in init.py since there are problems on finding the module.
Right now, I get the problem "'nvec (counts) have to be positive'".
I have no idea to fix it.

I'm using python3 and IDE is VScode.

here are my command and log from running on terminal.
python examples/example_gym_traffic_random.py
Traceback (most recent call last):
File "examples/example_gym_traffic_random.py", line 9, in

assert (np.array(nvec) > 0).all(), 'nvec (counts) have to be positive'
AssertionError: nvec (counts) have to be positive

And, I also changed the code in the statement in traffic_env. I think the problem is cause from that statement. But, if I did not change the method, it will show me the error of "AttributeError: module 'gym.spaces' has no attribute 'DiscreteToMultiDiscrete'"
the old one:
self.action_space = spaces.DiscreteToMultiDiscrete(
spaces.MultiDiscrete([[0, len(light.actions) - 1] for light in self.lights]), 'all')
I changed to this:
self.action_space = spaces.multi_discrete(
spaces.MultiDiscrete([[0, len(light.actions) - 1 ] for light in self.lights]), 'all')

I want to play around with the tool, but when I run the example: python examples/example_gym_traffic_dqn.py I get an error saying python cannot find the traci module.

I've been going through the installations steps mentioned by this repo readme before running the file, but I can't seem to figure out how to fix this.

What can I do from here?

whenever I try to run the examples I get the following error.
No module named 'dqn'

Dear Ben,

In my case, I had several errors. What kind of Gym version did you use ?

I used the following packages.

gym (0.8.2)
gym-pull (0.1.7)
tensorflow (1.0.1)
keras-rl (0.3.0)
sumo(0.29.0)

I got errors below.

I have the next error, in the example: "example_gym_traffic_dqn". Could you help me?
