Minimum Requirements

• SUMO 1.5.
• RLLIB RAY 0.8.2

Tested with

• Eclipse SUMO Version 1.9.2
  • With 1.9.2 the options
    • scenario_config['sumo_config']['sumo_connector'] = 'libsumo' with scenario_config['sumo_config']['trace_file'] = True does not work, but the bugh has already been fixed in SUMO issue 8671. If you need to enable SUMO tracing with 1.9.2, you need to use scenario_config['sumo_config']['sumo_connector'] = 'traci'
• RLlib Version 1.3.0

Installation

• Install: pip3 install . from the root directory, or python3 setup.py install
