guys im triying to use the GTK+ library for a python project.

import sys
import gi
gi.require_version('Gtk', '3.0')

but I get the error:
>File "d:\Code\python\Media player\test.py", >line 2, in <module>
> import gi
>ModuleNotFoundError: No module named 'gi'
I already installed the vext.gi

Requirement already satisfied: ruamel.yaml>=0.11.10 in c:\users\anon\appdata\local\programs\python\python39\lib\site-packages (from vext>=0.7.4->vext.gi) (0.17.4)
Requirement already satisfied: ruamel.yaml.clib>=0.1.2 in c:\users\anon\appdata\local\programs\python\python39\lib\site-packages (from ruamel.yaml>=0.11.10->vext>=0.7.4->vext.gi) (0.2.2)

any ideas?
