ClassFactory()

Hi Zoran,
I used to use the Visibility plugin but now it doesn't want to load with the following error -
Couldn't load plugin 'ViewshedAnalysis' due to an error when calling its classFactory() method
ModuleNotFoundError: No module named 'plugins.processing'
Traceback (most recent call last):

Hello,
This is a strange issue that was normally fixed some time ago. I can see that you have an old QGIS version : upgrade to 3.30+ and reinstall the plugin to be sure.

Hello Zoran,
Have been experiencing the same issue for some weeks now, and upgrading QGIS to 3.30+ sadly didn't do the trick
Thank you for your time and your amazing plugin

Answer 3 · 2023-11-30T10:18:41.000Z

Hi, same issue here. I'm using QGIS 3.34, and reinstalled the plugin several times but keep having this error, even tried with earlier versions of QGIS but always with the same result. Other plugins are working fine though. Any help would be much appreciated, thanks!

Answer 4 · 2023-11-30T15:05:31.000Z

OK - I'll take this into account for the new update.

Answer 5 · 2024-01-24T09:06:24.000Z

Yes been trying it in different versions 3.4, 3.8, 3.3 - problem still persists.

Answer 6 · 2024-02-12T09:12:51.000Z

Same problem in 3.34. I changed line 26 in viewshed_raster.py and line 11 in viewshed_index.py from from plugins.processing.gui import MessageBarProgress to from processing.gui import MessageBarProgress and reloaded the plugin. Now it works after only these two changes... Great Plugin thanks

Answer 7 · 2024-02-12T10:35:36.000Z

Thanks a lot for this solution! I hope to find some time soon for an update of the plugin...

Fixed in 1.9 version (pending approval)
