I did all, that was written on the wiki page. And I used image from the wiki page. Then I click autotile to ON in panel. Next, for example, I want to use a Simple layout. I select this region on Tileset view, click Setup autotile, then, I need to select each tile in this region and enter group id? And then I try to paint this autotile? but this doesn't work either. Anyway? I tried many times in many ways, but autotile absolutely not working!

It should work after you click on setup autotile, so long as the autotile script is set, I use it myself so it definitely works. By default the autotile script should be the one at res://addons/fabianlc_gpu_tilemap/autotile scripts/default_autotile.gd, if the autotile script property of the gputilemap node doesn't have anything for some reason it can't work, if you really think there's something broken you can open an issue on github and send a project where you can reproduce the issue.
