可以先看看 有沒有現成的方法 可以加進 ML app 。利用 pre-trained models，不需要自建models。

Example :

Aucnet is the largest real-time car auction service in Japan, serving over 30K dealers
and running auctions worth nearly $4 billion dollars a year.

過去 : 需要上傳車子各部位的照片並且標記，相當麻煩耗時。
現在 :　drop a bunch of unclassifiedphotos and checks if the model
and parts are classified by the system correctly

注意: 檔名不行為 中文 ，不然無法上傳圖片

Think about : Fill out a form or upload images which user experience is
better?
