[Qgis-user] spatial analysis toolbox - testing for autocorrelation

 Hi Francesca,
Sorry for the confusion.

FYI, I recently installed the 3.28 .msi QGIS from the QGIS.org website and geopandas is installed. You may just want to update your QGIS. I did not use the OSGeo4W installer, as that was giving me missing .dll errors.
If you want to persist with your current install, I think you want to do the following:
Open the 'Command Prompt' program (go to the start menu and search for it)
When it opens you will this prompt:     C:\Users\your_user_name>   From file explorer drag and drop the 'python.exe' onto the Command Prompt window. It should list the path to the python.exe file. You then want to press enter. That should log you in to an interactive python terminal and change the prompt to '>>>'.    Type in:   import geopandas    and press enter. That should give you a 'ModuleNotFoundError'. 
If it does not give you an error and instead just goes to the next line, you know that geopandas is installed. You can enter: exit()  and press enter, and you can close the Command Prompt window.

If you get the 'ModuleNotFoundError' error, press the up arrow and it should bring up the path to the python.exe file again.
Then enter:   -m pip install geopandas  Then press enter.That should bring up a long list of installation stuff, hopefully none of it is red. You can then press the up arrow twice to get the path to the python.exe and press enter to start python. Then try importing geopandas again as above.

 Thank you both! I checked that out and tried the suggested installing procedure.. but I can't get the command prompt where to type "pip install geopandas".I think I'm still missing a piece, I'm not so familiar with the python environment as you can assume.
These are the steps I followed:

--->

Then I clicked on "python3.dll", which downloaded the file I tried to open - but got me just another error message in QGis (saying that is an invalid data source).I searched online for other tips and tutorials, but (besides another procedure using fiona) I haven't found anything more specific on this one.
Should I go into the "Scripts" folder and click on "pip.exe" or "pip3.exe"?Thanks again for your time and any other inputs you may have!Francesca

 Hi Francesca,
If you don't know how to install Geopandas, I would like to add to what Paolo said. Geopandas needs to be installed in the python that QGIS is using.You can check the location of the python installation by going to the overall preferences for QGIS (command comma on a Mac, probably control comma on other systems.) 
>From the System tab scroll to the bottom to find the "Current environment variables" scroll down to find PYTHONHOME.This documentation page shows you more with pictures:
https://docs.qgis.org/3.28/en/docs/user_manual/introduction/qgis_configuration.html#system-settings
Then in Finder or Explorer, etc. you want to find  location in the file system. On a Mac you will need to right click on QGIS in your applications folder and show package contents.  Then continue through the path and double click to open the python3 file.This will bring up a python prompt where you want to type:   pip install geopandas   Then press enter/return. It will run for a while and hopefully say that you successfully installed geopandas. You will probably need to restart QGIS after that.

You have to install geopandas.
Cheers.
