I have done eyes detection in OpenCV using eye.xml Haarcascade classifiers but have no idea how to do it using Tensorflow.
If you want to detect eyes in what I assume would be photos, you can always use Mask R-CNN. Since you just want to detect eyes, you can use something called the COCO dataset. The Common Objects In Context is a collection of thousands of different objects, including eyes and faces, that can help detect the features you want in a photo.
