Hi David, let's try to debug the error with OTB 6.7. Indeed to use random forests classifier the correct way to set it is with '-classifier rf' option. And Random forests has not been removed in the last version and the way it is set from the TrainImagesClassifier did not change neither. In this case the random forests algorithm from opencv is used internally.
Can you run otbcli_TrainImagesClassifier without arguments to display the application documentation and tell me what classifier are listed as available in the documentation? It can also be related to a configuration issue with the superbuild. Can you check that you compile and install OpenCV with the superbuild? Can you post your CMakeCache.txt file? and also the output of the OTB configuration (you can find it in superbuild_build_dir/OTB/src/OTB-stamp/OTB-configure-*.log? Regarding OTB unit test, OTB is test on a nightly basis on Win/Linux/Mac. The log from the tests are available publicly: https://dash.orfeo-toolbox.org/index.php?project=OTB I don't see currently issues with the TrainImagesClassifier but I perhaps miss something (I've tested on my platform that the test related to random forests currently passed). Let's check your configuration and see Le mer. 12 sept. 2018 à 14:37, <davidmichea.unis...@gmail.com> a écrit : > Hi, > > I have a problem with otbcli_TrainImagesClassifier. > > I have 2 version of OTB installed : > > - one is 5.10.1 delivered in binary package for ScientificLinux 7.2 > - the other is the 6.7.0 build from source (Superbuild) yesterday > > I launch this command to use a random forest classifier on my dataset : > numactl --cpunodebind=1 --membind=1 otbcli_TrainImagesClassifier -io.il ./ > 9_bands_2020200_ATTRIBUTES.tif -io.vd ./INPUT/9_bands_2020200_SAMPLES.shp > -sample.mv 10000 -sample.mt 10000 -sample.bm 0 -sample.vtr 0.5 -sample.vfn > class -classifier rf -rand 1 -io.out ./rfModel.txt -io.confmatout ./ > rfConfusionMatrix.csv > (forget about numactl: not relevant here) > > > - when I use the 5.10.1 version, I got this error message : > > 2018 Sep 12 13:36:54 : Application.logger (INFO) Sampling rates... > 2018 Sep 12 13:36:54 : Application.logger (FATAL) > 2018 Sep 12 13:36:54 : Application.logger (FATAL) Missing arguments in > strategy.constant.nb to process sampling rates > 2018 Sep 12 13:36:54 : Application.logger (FATAL) The following error > occurred during application execution : > /home/otbval/Dashboard/src/OTB/Modules/Applications/AppClassification/app/otbMultiIm > ageSamplingRate.cxx:250: > itk::ERROR: Fatal error caught.
