how to solve this error

Looking at the error is that the game UI is not open, is your operating system macOS? Your game is Cities: Skylines or Stardew?

macOS , use this command

python runner.py --envConfig "./conf/env_config_chrome.json"

Sorry for the confusion. As shown in the software README, the software part experiments are only supported and tested on Windows. MacOS has different resolutions, layouts and logits for switching windows, we did not do the adaption so far.
