data_test

Reference data for kornia's test suite. kornia's conftest.py data fixture loads these files, pinned by commit SHA in testing/reference_data.py.

Formats

The .safetensors files are the current format. kornia reads them with kornia.core.load_safetensors, with no pickle and no extra dependency.

The .pt files are the original pickles. They stay because older kornia commits pin them by SHA. Each .safetensors file holds the same tensors as the .pt file with the same stem: same dtype, same shape, and the same bit pattern. Its __metadata__ names the source blob under converted_from.

What the conversion changed besides the container:

• String entries (source, Original_README) moved to __metadata__ under the same key.
• knchurch_disk.pt stores disk1/disk2 as a one-element list[DISKFeatures]. They are flattened to disk1.keypoints, disk1.descriptors and disk1.detection_scores, and the same for disk2. kornia's fixture rebuilds the list.
• loftr_outdoorr_tentatives1 (a misspelled key) was dropped from loftr_outdoor_and_homography_data. It is bitwise equal to loftr_outdoor_tentatives1.
• Every tensor is stored contiguous, and requires_grad is not stored.
