Cannot activate OTB in QGIS 3.28.4
Description
I have been trying to properly install OTB 8.1.1 in QGIS for Windows 10 Pro to no avail. It seems it is installed, but when I try to activate it in Process Toolbox settings there is no checkbox to activate the module and when I enable the plugin I get an error message.
Steps to reproduce
I installed QGIS 3.28.4 using OSGeo4W. I downloaded OTB 8.1.1. installation files and followed the instructions found here: https://docs.qgis.org/3.28/en/docs/user_manual/processing/3rdParty.html
I made sure the paths are correct in Process Toolbox settings, and I still cannot see the checkbox to activate.
When I try to enable the plugin in the installed complements window, I get the following message:
CRITICAL Traceback (most recent call last): File "C:\OSGeo4W/apps/qgis-ltr/./python\qgis\utils.py", line 423, in startPlugin plugins[packageName] = package.classFactory(iface) File "C:\qgis-plugins\qgis-otb-plugin\otb__init_.py", line 37, in classFactory from .OTBPlugin import OTBPlugin File "C:\OSGeo4W/apps/qgis-ltr/./python\qgis\utils.py", line 888, in _import mod = _builtin_import(name, globals, locals, fromlist, level) File "C:\qgis-plugins\qgis-otb-plugin\otb\OTBPlugin.py", line 26, in from .OTBAlgorithmProvider import OTBAlgorithmProvider File "C:\OSGeo4W/apps/qgis-ltr/./python\qgis\utils.py", line 888, in _import mod = _builtin_import(name, globals, locals, fromlist, level) File "C:\qgis-plugins\qgis-otb-plugin\otb\OTBAlgorithmProvider.py", line 39, in from otb import OTBUtils File "C:\OSGeo4W/apps/qgis-ltr/./python\qgis\utils.py", line 888, in _import mod = _builtin_import(name, globals, locals, fromlist, level) File "C:\qgis-plugins\qgis-otb-plugin\otb\OTBUtils.py", line 37, in from processing.core.ProcessingLog import ProcessingLog File "C:\OSGeo4W/apps/qgis-ltr/./python\qgis\utils.py", line 888, in _import mod = _builtin_import(name, globals, locals, fromlist, level) ModuleNotFoundError: No module named 'processing.core.ProcessingLog'
I have reinstalled QGIS, python libraries at least twice; tried to install OTB files directly to C: directory and changed paths accordingly, and even tried OTB 7.0.0 and still get the same error.
