Which Deep Learning Model can we use?

Hi Team,
Can you guys help with which deep learning model is used. Its for educational purpose, we have this competition as a course project in Data Mining and analytics course.
We have found deep ranking model is good but, we are unable to give directory of images as input while testing the model. Can anyone help us with this?
Or if u have another method which is better please help us out with this…
Thank You…
