1 year ago Hi @DOPEMANdd,
-
The
comp-1branch was used for 2022 NeurIPS Driving Smarts competition and has since been archived, with no further updates expected. -
Going forward, please use the latest code version from the master branch. The latest code version sidesteps the
sumo.tools.traci.exceptions.FatalTraCIError: Connection closed by SUMOerror. -
If you are interested in training and benchmarking your agents, please consider using the latest Driving Smarts 2023.1 & 2023.2 and Driving Smarts 2023.3 benchmarks.
High Level Description
When I am training in the comp-1 branch, the program always breaks, how to solve this problem?
Version
comp-1
Operating System
ubuntu22.04
