SPIDER-Skin Model
Model Description
SPIDER-skin model is a deep learning model trained for patch-level pathology classification, specifically for skin. It is part of the SPIDER dataset initiative, which provides a large, high-quality, multi-organ pathology dataset with expert-annotated labels.

How to Get Started with the Model
Model works with 1120×1120 patches. Use the following code snippet to load and use the model:
from transformers import AutoModel, AutoProcessor
from PIL import Image
model = AutoModel.from_pretrained("histai/SPIDER-skin-model", trust_remote_code=True)
processor = AutoProcessor.from_pretrained("histai/SPIDER-skin-model", trust_remote_code=True)
image = Image.open("path_to_image.png")
inputs = processor(images=image, return_tensors="pt")
outputs = model(**inputs)
print(outputs.predicted_class_names)
