Problem @ symbol in python file

[Julesghes]

I have ubuntu 21.10, and I moved files .inx and .py in inkscape extention.

I restarted inkscape, and I launched isometric transformation, but I had an error on the 164 line of the axonometric_projection.py file.
So, i imported numpy and I removed "tr = transform @ effect_matrix" with "tr =np.dot(transform, effect_matrix)" and it works.

I share my experience

Previously, on my old laptop (unbutu 22.04 LTS), I enjoyed isometric transformation and I didn't need to do that, curious.
Thanks for your extention

This sounds like it could be issue #15. Which version of Inkscape are you using?

Also, Ubuntu 21.10 is an interim release, which means it is only supported for a short period. Have you considered updating to Ubuntu 22.04 LTS?

[Julesghes]

Now, the extension does the job pretty well, since I removed @ operator.
I don't need to updating

The version is :
Inkscape 1.1.2 (0a00cf5339, 2022-02-04)

Yeah, that's an older version. The last supported version of this extension for Inkscape 1.1.2 is v2.1 (as noted in the README). You might want to consider getting Inkscape 1.2.2, but if this works for you, that's fine too of course.
