Tensorflow Version and Pretrained Model

Hi, I am just wondering which Tensorflow version you used, and do you by any chance have a ready-to-use pre-trained model?

I am looking for a ready-to-use program that can classify a name with the corresponding country origin, if you know of any other solutions that would be very helpful as well! I don't want to use NamSor because I wish to run it offline.

Thanks!
