Hi Moritz. First of all thank you for your very quick answer. I tried both suggested solution. The first one, try to manually change the script, didn't work. But luckily use OSGeo Live 10 is an option for me and I just finished to install the latest version and to download all the required add-ons. Both r.neighborhoodmatrix and i.segment.uspo now work well :-)
