Sorry for ignoring you up to now, just to much on the platter right now.
Would it be feasible for you to make the data available, privately if
necessary ? The easiest (and lightest) would be just the csv output of
v.db.select on the training_map and the segments_maps.

_v.class.mlR segments_map=gbbb@PERMANENT
training_map=tainning@PERMANENT train_class_column=fd
output_class_column=vote output_prob_column=prob folds=5

_and the same error with this command:

_v.class.mlR segments_map=gbbb training_map=tainning
train_class_column=class weighting_mode=smv,swv,qbwwv -i_
The vector used was elaborated with i.segment.stats module.
An extract is here:
cat area perimeter fd
1 958 208 1.555034
2 24 22 1.945217
3 160 80 1.726846
4 2036 242 1.440904
5 25 26 2.024344
6 222 96 1.68966
7 8435 1012 1.530879
/cat /type Integer (9-0)
/fd /type double/real (25-9)
For the training area (t/ainning/), I use a simple vector with
numerical categories (named/"cate"/) and there are 11 features (just
for a trying). The type is in integer64 (10)

R messages are often not very explicit, unfortunately.
Could you provide us with the exact command line you use (If you
use the
GUI, you can get the command line by clicking the 'Copy' button
once
you've filled out all the parameters, or in the history of the
'Console'
in the Layer manager.) and an extract of the attribute data you
feed
into the module ?
