Model weights extracted below:

from timm.models.vision_transformer import _convert_openai_clip


path = "CLIP_ViT_L14_LAION_RS/epoch_20.pt"

model, _, preprocess_val = create_model_and_transforms(encoder, path, weights_only=False)

model_timm = timm.create_model("vit_large_patch14_clip_224", pretrained=False, num_classes=768)
converted = _convert_openai_clip(model.state_dict(), model_timm)
model_timm.load_state_dict(converted, strict=True)

filename = "vit_large_patch14_224_skyclip_50pct.pth"
torch.save(model_timm.state_dict(), filename)
md5 = hashlib.md5(open(filename, "rb").read()).hexdigest()[:8]
os.rename(filename, filename.replace(".pth", f"-{md5}.pth"))

The preprocessing transforms are:

Compose(

    CenterCrop(size=(224, 224))
    <function _convert_to_rgb at 0x707759392980>
    ToTensor()
    Normalize(mean=(0.48145466, 0.4578275, 0.40821073), std=(0.26862954, 0.26130258, 0.27577711))
