Error with GlobalVars

[Arantxa Ortiz]

Hello,

I am trying for the first time to start Qswat with the example data provided when downloading, but when I choose the folder containing the data, I can´t continue since there is an error with GlobalVars in phyton. How can I fix this?

Check your QSWAT+ log (button at bottom right of QGIS window, QSWAT+
tab). If you see somewhere a reference to matplotlib_scalebar then
replace gwflow.py with the attached. You will find gwflow.py in

C:\Users\<username>\AppData\Roaming\QGIS\QGIS3\profiles\default\python\plugins\QSWATPlus3_9\QSWATPlus


if you installed just for yourself, else in

C:\Program Files\<QGIS>\apps\qgis-ltr\python\plugins\QSWATPlus3_9\QSWATPlus

If this is not the problem send me the complete QSWAT+ log contents.

I also experienced this problem and was able to solve it by manually replacing the gwflow.py

This error is caused by some module not loading (probably not the
Parameters module). You need to look at the complete messages in the
QSWAT+ tab for the reason. Send me the complete QSWAT+ messages if you
can't solve it yourself.
