 ## Code Example
 Load an image from path './test_face.jpg'.
 
- *Write the pipeline in simplified style*:
-
-```python
-import towhee
-towhee.glob('./test_face.jpg') \
-  .image_decode.cv2() \
-  .face_embedding.deepface(model_name = 'DeepFace').to_list()
-```
-
-
-<img src="./image.png" height="200px"/>
-
 *Write a pipeline with explicit inputs/outputs name specifications:*
+from towhee.dc2 import pipe, ops, DataCollection
 
+p = (
+    pipe.input('path')
+        .map('path', 'img', ops.image_decode())
+        .map('img', 'vec', ops.face_embedding.deepface(model_name = 'DeepFace')))
+        .output('img', 'vec')
+)
 
-```python
-import towhee
+DataCollection(p('./test_face.jpg')).show()
 
-towhee.glob['path']('./test_face.jpg') \
-  .image_decode.cv2['path', 'img']() \
