Stuck on an issue?

Lightrun Answers was designed to reduce the constant googling that comes with debugging 3rd party libraries. It collects links to all the places you might be looking at while hunting down a tough bug.

And, if you’re still stuck at the end, we’re happy to hop on a call to see how we can help out.

Have you considered using environment.yml or requirements.txt?

See original GitHub issue

Did it ever cross your mind to use an enivronment.yml or at least a requirements.txt file? Or is it a local custom in your country not to include versions of each specific Python library / framework? 😜

I understand that you’re using the setup.py file to install it from source; however, you did not include all the specific versions at line 3.

Suggestion

Including all versions could have been useful. Including a requirements.txt would’ve been more useful. Including an enivronment.yml would’ve been even more useful. Using Docker would have been the ultimate solution. Please don’t expect your users to use trial-and-error to find the version of each specific dependency.

pip freeze is your friend. 😉

Anyway, I managed to resolve the dependencies by myself.

Is this a code that your repository is intended to run? It was taken from README.md.

Input

import sumo_rl
env = sumo_rl.env(net_file='sumo_net_file.net.xml', route_file='sumo_route_file.rou.xml', use_gui=True, num_seconds=3600)

Output

(… and keeps looping continuously with the same error)

You should replace net_file=‘sumo_net_file.net.xml’, route_file=‘sumo_route_file.rou.xml’ with actual existing files. A few networks and route files are available on nets folder.

It’s not clear what you’re trying to say. In any case, do you have any example code that your repository is intended to run? PS. The problem seems to be with your repository and not the “RL algorithms”. You’re missing dependencies.

SUMO-RL is repository that provides Gym and PettingZoo environments. It IS NOT a repository for running RL algorithms. Stable-baselines, RLlib, etc. ARE NOT SUMO-RL dependencies, and should not be installed by default when installing SUMO-RL.

An example of running a Tabular QL agent can be found here: See https://github.com/LucasAlegre/sumo-rl/blob/master/experiments/ql_4x4grid.py
