Hello,

I try to make a environment using below code.

import gym import minerl env = gym.make('MineRLNavigateDense-v0')

At this point, screen of game usually was visualized. However, It does not show up at MineRL 0.4.0 version. Other version shows a screen after that code.

Should I add more code to see screen?

Thank you

In MineRL 0.4, the code adds a xvfb-run command when launching Minecraft, which hides the window. The next release and current dev branch has removed this code, so upon running the above code you will see the window again. However, due to other changes, the window does not update like it did with 0.3.7.

If you want to see the frames, I recommend using cv2 and its imshow function to see the image in real time.
