33 checkpoints total (11 datasets x 3 trainer families)
release_index.csv with one row per checkpoint, including checkpoint path/hash/size, Base-to-Novel metrics (B/N/HM), and extracted experiment configuration fields
checkpoint files are organized under canonical paths: checkpoints/<trainer>/<dataset>/shots_<k>/<cfg>/model.pth.tar

This release intentionally excludes training/test logs and internal manifest files.

Intended Use

These checkpoints are intended for:

research reproducibility
base-to-novel prompt-learning comparison
checkpoint reuse with the original SpecPL training/evaluation codebase

Quick Usage (Official Repo)

Use these checkpoints with the official codebase.

bash

git clone https://github.com/Mlrac1e/SpecPL-Prompt-Learning.git
cd SpecPL-Prompt-Learning

# Set dataset/cache paths
export DATA_ROOT=path/to/data
export CLIP_ROOT=path/to/clip

# Checkpoint files in this release
ls /path/to/Output_Release_HF/checkpoints

Select the checkpoint path from release_index.csv, place it at the output location expected by the official scripts, and run the corresponding Base-to-Novel evaluation script from the repository documentation.

Training And Evaluation Context

Protocol: base-to-novel generalization
Shot setting: 16-shot
Datasets: 11 benchmarks used in the paper/repo

Limitations

These are raw training checkpoints, not end-user inference packages.
Results depend on the original environment/configuration and evaluation scripts.
Dataset licenses and access conditions follow each dataset's original terms.
