NLE crashing when run on WSL

russellw commented 2 years ago

🐛 Bug

NLE on WSL successfully installs, but crashes when I try to run it.

To Reproduce

Steps to reproduce the behavior:

Follow the steps in the Readme, under the heading "On a plain Ubuntu 18.04 distribution."
python -m nle.scripts.play

    (nle) a@DESKTOP-4B7M920:~$ python -m nle.scripts.play

        env.render(FLAGS.render_mode)
    TypeError: render() takes 1 positional argument but 2 were given

The above was the output on the first attempt. I noticed in another issue report, a remark to the effect that gym 0.24 has become stricter, so I tried downgrading it to 0.23 and rerunning NLE. Now it crashes with a different error:

    from nle._pynethack.nethack import *  # noqa: F403
ModuleNotFoundError: No module named 'nle._pynethack'

Expected behavior

Play NetHackStaircase-v0 as a human. I also tried the command to run it in random mode, with similar results.

Hi @russellw, is this still an issue. It looks like NLE never properly installed.

Closing, feel free to reopen if the issue rears its head again.
