The Gym API changed and requires more parameters now. I think that was the issue when I ran it. The python have to be updated to account for this. If you are not super into python, dump the code and the error message into chatGPT and it will help you resolve it.

At some point Flexsim should probably update the tutorial code.

Fix the code. Its the Gym lib that is causing the issue, not the python version.

You can try with the attached version. Just remember to change the paths (as stated in the tutorial)

That should be fixed in the code I sent. Anyway chatGPT is your friend here, it will tell you what to change based on any error codes you give it. This is more related to python programming than Flexsim.
