 ## Code Example
 
-Load an image from path './towhee.jpeg'
-and use the pre-trained mpvit_base model to generate an image embedding.
-
- *Write the pipeline in simplified style:*
-
-```python
-import towhee
-
-towhee.glob('./towhee.jpeg') \
-    .image_decode() \
-    .image_embedding.mpvit(model_name='mpvit_base') \
-    .show()
-```
