Checkpoints

The Files and versions tab contains .pth checkpoints for MaskCLIP and related OpenSDI baselines. For MaskCLIP evaluation, download one of the MaskCLIP_sd15_*.pth checkpoints and use it with the OpenSDI codebase.

Example:

hf download nebula/MaskCLIP-weights MaskCLIP_sd15_20241103_17_45_16.pth --local-dir weights

Then set --checkpoint_path in test.sh to the downloaded checkpoint path, for example:

--checkpoint_path "weights/MaskCLIP_sd15_20241103_17_45_16.pth"
