Hi everyone, I am a beginner to using ML Agents to simulate an environment for DL I am trying to trial runs by tinkering through different values between the action space and keep encountering this issue when attempting to run a new trial. I've tried mlagents-learn --force and mlagents-learn --run-id=newtest but both prompt the same error message. Using linux, I am aware of a similar bug occuring in older versions (https://github.com/Unity-Technologies/ml-agents/issues/1505) but solutions didn't fix it. Tried restarting everything but still The error message reads: mlagents_envs.exception.UnityWorkerInUseException: Couldn't start socket communication because worker number Couldn't start socket communication because worker number 0 is still in use. You may need to manually close a previously opened environment or use a different worker number. is still in use. You may need to manually close a previously opened environment or use a different worker number. Couldn't connect to trainer on port 5004 using API version 1.5.0. Will perform inference instead. UnityEngine.Debug:Log (object) Unity.MLAgents.Academy:InitializeEnvironment () (at Library/PackageCacheemail@example.com/Runtime/Academy.cs:459) Please let me know how I can fix this!
