Cannot render environments #43

Open stjepangolemac opened 3 years ago

stjepangolemac commented 3 years ago

I'm trying this on a MBP.

Maybe I'm doing something completely wrong. I modified the test_step test by adding a env.render(). The test fails with this error:

Caused by:
  process didn't exit successfully: `/Users/user/dev/gym-rs/target/debug/deps/gym-d47e830353331d9d 'tests::test_step' --nocapture` (signal: 6, SIGABRT: process abort signal)

Are all environments supporting rendering?

EDIT: I've just tried to render the VideoPinball one, it also crashes. Not sure why but FrozenLake works, probably because it only renders some characters to terminal.
