train_model yaml scaner error

[LAADHARI]

hello.
i am using latest instable master version of gaia & essentia
i tuned /usr/local/lib/python2.7/dist-packages/gaia2/scripts/classification/classification_project_template.yaml

then
user@localhost $python /usr/local/lib/python2.7/dist-packages/gaia2/scripts/classification/train_model.py groundtruth_example.yaml filelist_example.yaml genret genre_t resmod 2>output

i end up with :
resmod.results.html empty file.
many genre_t/datasets/*.db
many genre_t/results/*.{result,param}

LAST console outputs:
