Hi Paolo and list,I am using the Segmentation algorithm on Linux without major problems. (OTB 6.6 and now 7.0 with QGIS 3.10). But indeed it does not work out of the box: Even when raster output does not not apply to the Segmentation alg , a "bogus" value would have to be entered in the output box to avoid an exception and get the alg running.
Also, the OTB processing provider settings interface has some issues:when I try to change configuration values (namely the amount of max RAM ), I get an error " argument has unexpected type 'int' "

Hi Paolo,I'm using OTB (6.6.1 and 7.0.0) with QGIS 3.10.0, without any problem, but I'm on Windows.About the issues you reported (".raster.out.tif" and vectors not being loaded), I think this thread can explain almost all of them (I had the same doubts some time ago):https://gitlab.orfeo-toolbox.org/orfeotoolbox/qgis-otb-plugin/issues/30 Best regards, Pedro VenâncioPaolo Cavallini <[email protected] <mailto:[email protected]>> escreveu no dia terça, 3/12/2019 à(s) 12:00:Moreover, the vector resulting vector layer is not automatically loaded.
