Same as https://huggingface.co/HuggingFaceM4/siglip-so400m-14-384-flash-attn2 with two changes:
- increase max resolution to 980 x 980 (instead of 384 x 384) by interpolating the position embeddings
- implement the strategy in NaViT to allow a/ variable resoltion images, b/ aspect ratio preserved images
These changes only apply to the vision tower. No changes to the text tower.
Implementation is fully backward compatible to https://huggingface.co/HuggingFaceM4/siglip-so400m-14-384-flash-attn2 -> just don't specify the patch_attention_mask
Usage:

DEVICE = torch.device("cuda:0")
PATCH_SIZE = 14
pixel_values = torch.randn(2, 3, 28, 42, dtype=torch.bfloat16, device=DEVICE)
