I'm sorry, but I haven't had the time, yet, to test here with you data.
I'll do that ASAP, but workload is very high at the moment.

There could be conflicts of Python libraries, but normally, when you
run the modules directly from GRASS GIS they should use the Python
libs that come with GRASS GIS. You are not actually running v.class.mlR
from QGIS, instead of directly from GRASS GIS, or ?

I'll try directly in GRASS GIS on Linux, here. Sorry, just bad timing
right now.
