[GRASS-user] r.futures not working

[Tom Hackbarth]

Dear grass users,

I am trying to work my way through the r.futures workshop (
https://grasswiki.osgeo.org/wiki/Workshop_on_urban_growth_modeling_with_FUTURES#Potential_submodel),
but as soon as I get to the point of using the first r.futures module -
r.futures-potential I come to a dead end.

This is the message I get:

___________________________

r.futures.potential input=sampling at practice1 output=potential.csv
columns=devpressure_0_5_92,road_dens_perc,forest_1992_smooth_perc,dist_to_water_km,dist_to_protected_km
developed_column=urban_change_clip subregions_column=counties
Computing model...

  File "D:\Programme\apps\Python37\lib\subprocess.py", line

    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified)


_____________________________

There seems to be a problem with the Python code. I also tried to work it
out on linux manjaro, but I get more or less the same error message in the
End.

Is there anyone who can help me on this? I came not even close to
repairing the error, so I am happy about any advice one can give me.

Thank you in advance.

Best regards

Tom
