[Windows Support]module 'os' has no attribute 'getpgid'

When running env.reset(), I encounter this error:

Initializing new Carla server...

AttributeError: module 'os' has no attribute 'getpgid'

I think this is because the os library does not support the getpgid function in windows. Are they any workarounds for this issue?

Ohh. Okay. Yeah, the setsid is also not available on Windows. I unfortunately don’t yet have a Windows machine setup to test this out now. The solution is to remove the preexec_fn=os.setsid argument to Popen. I have update my comment above(https://github.com/praveen-palanisamy/macad-gym/issues/32#issuecomment-779564218) to include this change as well for Windows support. Please give it a try with this change and post what you find.
