[GRASS-user] problems with r.learn.ml and python 3.7

GRASS GRASS user

Dear GRASS users,
I am having problems to use r.learn.ml. I am using OSGeo win10 version (7.6.1)
I installed scikit-learn using pip:

C:>python3 -m pip install scikit-learn

Requirement already satisfied: scikit-learn in c:\osgeo4w64\apps\python37\lib\site-packages (0.21.2)

Requirement already satisfied: scipy>=0.17.0 in c:\osgeo4w64\apps\python37\lib\site-packages (from scikit-learn) (1.1.0)

Requirement already satisfied: numpy>=1.11.0 in c:\osgeo4w64\apps\python37\lib\site-packages (from scikit-learn) (1.16.3)

Requirement already satisfied: joblib>=0.11 in c:\osgeo4w64\apps\python37\lib\site-packages (from scikit-learn) (0.13.2)

But when I ran the r.learn.ml I got this message:

r.learn.ml group=lsat7_2000 trainingmap=landclass96_roi output=rf_classification classifier=RandomForestClassifier n_estimators=500

ERROR: Scikit learn 0.18 or newer is not installed

(Sat Jun 22 13:55:02 2019) Command finished (4 sec)

I modified the python-core.bat file to point to python 3.7 this way:

SET PYTHONHOME=%OSGEO4W_ROOT%\apps\Python37

PATH %OSGEO4W_ROOT%\apps\Python37\Scripts;%PATH%

But GRASS is still using Python 2.7 as shown in the Python shell:
Python 2.7.14 (v2.7.14:84471935ed, Sep 16 2017, 20:25:58) [MSC v.1500 64 bit (AMD64)] on win32

How can I make sure GRASS uses Python 3.7

Thanks in advance.

You will need to switch to GRASS GIS 7.7.dev (upcoming 7.8) for Python3 support.

Binaries should be available from here
https://grass.osgeo.org/download/software/ms-windows/
--> OSGeo4W

but at time the compile chain is broken.
Maybe others can shed light on where to currently get G77 for Windows...

Best,
Markus

any chance to get back winGRASS dailys before? so we'll be able to flood
github issues with winGRASS issues... :wink:

yes, I will have time after July 1. Ma
