        num_semantics_stuff_classes=len(self.semantics.stuff_classes),

To Reproduce Steps to reproduce the behavior: either command : ns-train semantic-nerfw --data data\nerfstudio\poster nerfstudio-data or even : ns-train semantic-nerfw --data data\blender\lego --pipeline.model.near-plane 2. --pipeline.model.far-plane 6. blender-data
