+```python
+from towhee import DataLoader, pipe, ops
+p = (
+    pipe.input('image_path')
+    .map('image_path', 'image', ops.image_decode.cv2())
+    .map('image', 'vec', ops.image_embedding.timm(model_name='resnet50'))
+    .output('vec')
+
+)
+
+for data in DataLoader(ops.data_source.glob('./*.jpg')):
+    print(p(data).to_list(kv_format=True))
+
+# batch
