[Qgis-user] Raster Merge issue

[Irene McGoldrick]

I have no programming background, so please excuse me if this is an
incredibly basic question. I have tried turning it off and turning it back
on again.

I have been successfully merging raster layers over the past week using
Raster>Miscellaneous>Merge. It is no longer working for me. I can
achieve the same results by using Build Virtual Raster but I'd like to
understand what's happening and fix it if I can. I'm using the same raw
data to try to merge as I was successfully using during the week - nothing
has changed.

This is the error message I'm getting

In the log I am getting a message


2024-01-22T17:23:37     INFO    No module named 'remotior_sensus'


Also

2024-01-22T17:23:39     WARNING    Semi-Automatic Classification Plugin :
Warning. Python library remotior_sensus was not found and was automatically
downloaded, but SCP may not work properly. Please, install the required
Python library remotior_sensus following the user manual.


Not sure if they are related or not. I have uninstalled and re-installed
the Semi Automatic Classification Plugin. I'm working off Mac OS. I have
tried searching remotior_sensus in the user manual but I'm not getting
anything back for it.


Any help much appreciated.
