struct.error: unpack requires a buffer of 44 bytes

Hi, I'm trying to run a spatial autocorrelation but every time I tried i got the following error:

Hope you can help me to solve this problem.

You may try the version 0.7 with qGis 3.22 ... this may solve the issue ?

[Marcoortiz22]

Not really. I installed QGIS 3.22 and visualist version 0.7 in a fresh install of Manjaro Linux (KDE version). However, everytime I launche QGIS with the plugin activated QGIS died.

I got the message after the following steps: first attemp to activate visualist plugin I got a warning of missing scipy, so I did pip install scify Then missing pandas, so I did pip install pandas The next warning was about shapely, so I did pip install shapely After succesfully installed I got the following message in terminal:

Warning: link #path2410 is undefined! Warning: link #path2410 is undefined! Warning: link #path2410 is undefined! Warning: QString::arg: Argument missing: Shapefiles, .shp .SHP

:1: DeprecationWarning: setapi() is deprecated QGIS died on signal 11zsh: IOT instruction (core dumped) qgis Any idea?

Thank you for the feedback, it works with the LTR version on windows and osx. I did not try on linux. I'll try to do so, as soon as I can.
