For virtual Framebuffer (headless testing) I'm using Xvfb
with PyVirtualDisplay
and it's working fine in Ubuntu but showing error in Windows7. here is part of code where problem is occurring.
from pyvirtualdisplay import Display
display = Display(visible=1, size=(300, 400))
display.start()
but when I run same command in Windows, I get this error
Traceback (most recent call last):

Program install error!
I think my program is not able to find xvfb program/library ? I installed xvfbwrapper (https://github.com/cgoldberg/xvfbwrapper) but problem still remain same. again I think xvfbwrapper is different from xvfb?
Any alternative for Windows platform which can do headless testing (virtual framebuffer)
However, the Gym is designed to run on Linux. Even though it can be installed on Windows using Conda or PIP, it cannot be visualized on Windows. If you run it on a headless server (such as a virtual machine on the cloud), then it needs PyVirtualDisplay, which doesn't work on Windows either.
Xvfb (short for X virtual framebuffer) is an in-memory display server for UNIX-like operating system (e.g., Linux). It enables you to run graphical applications without a display (e.g., browser tests on a CI server) while also having the ability to take screenshots.
You get an error because command Xvfb
was not found. Xvfb is X virtual framebuffer which is not a part of Microsoft Windows 7.
