An error appears a few seconds after the launch of the algorithm ; This error is not well documented : "(FATAL): itk::ERROR: Failed to open GDALDataset file C:\Documents\test_classif_b_indices_fin_2.svm_samplesValid_1.shp : " There is nothing after the ":" I'm using OTB 6.4.0 on windows 10. I'm using SVM algorithm to produce my model with a command like this : otbcli_TrainImagesClassifier ^ -io.il D:\Documents\image.tif ^ -io.vd D:\Documents\training.shp ^ -sample.vfn class ^ -sample.vtr 0 ^ -classifier libsvm ^ -classifier.libsvm.k linear ^ -io.imstat D:\Documents\image_stats.xml ^ -io.out D:\Documents\model.svm When I use this function from the library in Monteverdi, the error does not appear, the model is produced correctly. Could you tell me if this is a setup problem? or if it's a bug related to itk, or GDAL?
