I get a weird error when i test my installation using

python -m spinup.run ppo --hid [32,32] --env Walker2d-v2 --exp_name installtest

There appears to have been an error in your experiment.

Check the traceback above to see what actually went wrong. The traceback below, included for completeness (but probably not useful for diagnosing the error), shows the stack leading up to the experiment launch.

The “Change python version system-wide” section in the link provided by @justindixon appears to be the right solution. @HareshMiriyala, @venkat-kittu, try it and report back?
