Fix env.render(mode="human")

[johan-gras]

Problem description:
env.render() or env.render(mode="human"), wasnt't working anymore after this change in #43

This change was IMO an error and should be reverted, this is the purpose of this commit.
Should resolve #92

Please can you take a look @harrisse to this really small PR. Thanks.

Apologies for the delay and thanks for the ping. This line should print the human-readable result when there is not an output path: https://github.com/Kaggle/kaggle-environments/blob/master/kaggle_environments/main.py#L345

Can you confirm the command you're using to run kaggle-environments so I can reproduce on my end?

Setting to requesting changes pending further discussion.

Can you confirm the command you're using to run kaggle-environments so I can reproduce on my end?

from kaggle_environments import make, evaluate, utils
env=make("connectx", debug=True)
env.render(mode="human")

Expected behavior: print the env
Current behavior: doesn't do anything
