I have installed Tryton 6.0 client via pip3 on a fresh Tumbleweed system and MATE desktop, Python 3.8.8 When attempting to connect to the demo server it crashes with: ModuleNotFoundError: No module named ‘pygtkcompat’ As this was an issue for Tryton 5.0 ([Why does Tryton still needs pygtkcompat library? - #13 by ced](https://discuss.tryton.org/t/why-does-tryton-still-needs-pygtkcompat-library/1608/13)), I seem to remember that full Python3/GTK3 compatibility was planned for Tryton 5.2? ---

> [@coogor](#): > > I seem to remember that full Python3/GTK3 compatibility was planned for Tryton 5.2? A quick search on the CHANGELOG of the tryton client let me to this changeset: [https://hg.tryton.org/tryton/rev/3cb5828e5ec2/](https://hg.tryton.org/tryton/rev/3cb5828e5ec2/) Which landed on tryton 5.2. But there is still some code there to avoid dulication of generictree.

First of all - please dont edit my postings.

So for how long do you plan to stick with this deprecated function? ---

> [@coogor](#): > > So for how long do you plan to stick with this deprecated function? For ever because it is not deprecated but a class to [ease implementing Gtk.TreeModel interface in Python](https://gitlab.gnome.org/GNOME/pygobject/-/blob/master/pygtkcompat/generictreemodel.py#L75) and because there is no point to have to maintain ourselve such tool. ---

This is free software, feel free to [provide a patch](https://www.tryton.org/develop) if you have one. For me [Welcome - openSUSE Build Service](https://build.opensuse.org/package/view_file/home:DocB:branches:devel:languages:python/tryton/000-pygtkcompat.diff?expand=1) works quite well ---
