CarRacing-v0 Window size issues

[tleyden]

When I run the following snippet in Jupyter Notebook:

import gym
env = gym.make('CarRacing-v0')
env.reset()
for _ in range(1000):
    env.render()
    env.step(env.action_space.sample()) # take a random action

It pops up a window that appears to be larger than the environment, with much of the window being clipped:

Is there a way to resize the window? Any workaround ideas?

Versions

• OSX Sierra
• gym==0.10.9
• Python 3.7.1

Here's a hack that i found to work. Change line 386 of car_racing.py to:
gl.glViewport(0, 0, WINDOW_W*2, WINDOW_H*2).

I believe the issue is that our mac screen sizes are too small for the assumed 1200x1000. Alternatively you can change the DPI.

Thanks! I'll give it a shot

This looks like a pyglet issue, what's the output of pip show pyglet?

I am running into the same issue.

By changing the line to gl.glViewport(0, 0, WINDOW_W*2, WINDOW_H*2), the window is much smaller but still the content is not fully visible (the reward-bar is not visible).

The output of pip show pyglet is

Thank you very much in advance!

To add onto clvoloshin's answer, in line 47 of car_racing.py, you can change the value of WINDOW_H to a lesser value. EG 800 works for me. Naturally you can change lines 46 and 47 to create a window that fits your needs.
