I think a porting to current versions is really needed.
Cheers.

there is the link in plugin manager:
https://github.com/nextgis/molusce/issues

yes, and to the new APIs. I'm not sure the original authors will upgrade
it, maybe you can ask them?
all the best

Indeed, in Ubuntu the maplotlib libraries do not have that module. This
works:
from matplotlib.backends.backend_qt4agg import NavigationToolbar2QT as
NavigationToolbar
(NavigationToolbarQT without the Agg at the end)

I checked on a Windows 7 machine with QGIS 2.18 standalone and the
plugin installs fine.

Any ideas how to straighten this out on Ubuntu?

Hi Micha,
thanks for your note. In fact, the plugin would need a bit of love,
especially upgrading it for the upcoming QGIS3.
Anyone interested?
All the best.

Re: [Qgis-user] MOLUSCE plugin error -> SOLVED

[Firman Hadi]

Hi all,

Just want to update.
I’ve finally managed to use the plugin.
The error was happened because I didn’t use same land use
class for the time series image.

Best regards,

Firman Hadi.
