If I switch to an other model file, it crashes when executing the instruction detector.trainModel(pc)  returning a Segmentation fault error. I have tried to execute the code with several other models, but the result is always the same. Also, I have checked the model files, and they contain the same information (almost same number of vertices, faces, no texture, etc.). Does anyone have the same problem? Regards Denis
