ModuleNotFoundError: No module named 'SBEnvironment'

[rl-2]

I was trying to run ./TestPythonHeuristicAgent.sh RandomAgent and got this error ModuleNotFoundError: No module named SBEnvironment.

I've tested on both Ubuntu and MacOS and it seems the error is cross-platform.

Hi Rodger, sorry for the late reply. The issue is fixed, please try again on Ubuntu.

Thanks, Cheng! The ModuleNotFoundError: No module named SBEnvironment issue goes away.

However, a new issue comes up after several agent runs:

running 1_01_01
agent 1 running
agent 2 running
agent 3 running
agent 4 running
agent 5 running
agent 6 running
agent 7 running
agent 8 running

That might be related to #4

it seems like the game server is not initialized. can u try to go to sciencebirdsgames/Linux and run java -jar ./game_playing_interface.jar first before running the agent? is the server successfully initialized? if not please also check if you are using java 13. Thanks.

Thanks, Cheng. The issue went away after initializing the server by java -jar ./game_playing_interface.jar.

Closing the issue.
