error occurred when drawing

[ZheliXiong]

hello,bro.i meet a problem after i choose the correct replay_roadnet.json and replay.txt file and click start.it says -start replaying - error occurred when drawing. i dont know is that my browser's problem?byw my replay.txt is empty,i dont know is that normal?

If your replay.txt is empty, it means you did not save the replay or some error occurs when running CityFlow. You can test your browser by running an existing replay_roadnet.json and replay.txt by running "frontend/download_replay.py".

How many steps did you run? You can output the total vehicle count in every step to see whether the simulation is working.

En, you should run the engine after you create it by "eng.next_step()".

hello! I meet the problem that the replaylogfile.json and replay.txt file can be loaded successfully, but it shows "drawing roadnet faeiled"!

I use the google browser, and I think these two file is correct.

Can you give me some suggestion about this problem? Or, can you tell me which browser you are use ? Thanks a lot!

Please check the roadnet file you uploaded in GUI corresponds to roadnetLogFile in config.json
