RQGIS3 on windows 10 python3 error

[coreysparks]

I just installed QGIS3 from OSGeo4w, and can get set_env() to work:

$root
[1] "C:/OSGeo4W64"

$qgis_prefix_path
[1] "C:/OSGeo4W64/apps/qgis"

$python_plugins
[1] "C:/OSGeo4W64/apps/qgis/python/plugins"

but when I try to get the algorithm information, I get a python3 error:

get_usage(alg = "native:centroids")
Error in python_config(python_version, required_module, python_version, :
Error 1033 occurred running C:/OSGeo4W64/bin/python3.exe
In addition: Warning messages:

This was because the Python interpreter was changed from Python36 to Python37 in the latest OSGeo4W update. Should work now again, I have tested a few native, saga, and grass functions.

Note to myself: replace the hard-coded paths to the Python binaries by the paths found in py3_env.bat.
