v0.14.2

[0.14.2] - 2026-02-24

New Classification Support: You can now train image classification models with LightlyTrain! See the classification documentation for more information.

Added

• Add
  classification support
• Add support for frozen backbone training in LTDETR and Picodet object detection
  models. Set model_args={"backbone_freeze": True} in train_object_detection to
  freeze the backbone and reduce VRAM usage.
• Add LTDETR support for DINOv3 ViT-B/L and DINOv2 ViT-L/B/G models. Pretrained weights
  are not yet available for these models.
• Add support for fine-tuning DINOv2 models for instance segmentation with the
  train_instance_segmentation command. See the
  instance segmentation documentation
  for more information.

Fixed

• Filter invalid bounding boxes in instance segmentation
• Fix incorrect logging of training times.
