Usage

python
from datasets import load_dataset

# Load baseline patches
dataset = load_dataset("dellacortelab/PANDA-PLUS-Bench", split="baseline")

# Access a sample
sample = dataset[0]
image = sample['image']      # PIL Image
label = sample['label']      # 0-3
slide_id = sample['slide_id']  # Slide identifier
