+```python
+from datasets import load_dataset
+
+def get_affinity_data():
+    data = load_dataset("Synthyra/ProteinProteinAffinity", split="train")
+    data = data.remove_columns(['pdb_id', 'source', 'kd'])
+    data = data.rename_column('pkd', 'labels')
+    data = data.shuffle(seed=11)
+    data = data.train_test_split(test_size=1000, seed=22)
+    valid = data['test']
+    train = data['train']
+    valid = valid.train_test_split(test_size=500, seed=33)
+    test = valid['test']
+    valid = valid['train']
+    return train, valid, test
