Creating a test on python with tensorflow

I am pretty new in python and in tensorflow, I am currently trying to do a machine learning project for super resolution. I trained the machine with photos of human faces, and now I want to add a Test file using the models I got from the tensorflow, but have no idea how to do that.

reference for the training project: http://ift.tt/2r4G7Kn.

After the training, I got 3 files, model.ckpt.index, model.ckpt.meta, model.ckpt.data.

Thanks for your help.
