Dear @antoine-galataud

Error happened when I run the run.py in a win10 enviroment.
The following is logs. Could you tell me how to fix it?
Best regards.

Hi @agl71, looking at the stack trace you provided it seems like some text message in the gym env contains non UTF-8 chars, which is not supported by protobuf (the communication protocol used for remote procedure calls in Ray).
Did you modify run.py to add some extra error messages in exceptions? Check also the encoding format of your file if you edited it (stick to UTF-8).
