Hi! on my machine GPy failes to build with the following error:

Is this related to python 3.9?

Definitely alive.

And still very widely used.

Just not got a single official maintainer currently. But feel free to continue contributing!

3.8.5 worked for me as well. However, it seems like there hasn’t been any activity for over two months now, so I’m wondering whether GPy is still alive.
