TF eager version training and testing

[matteo-dunnhofer]

To try the new TensorFlow Eager style, I decided to implement the old scripts using it. They are contained in the tf_eager folder whereas the old code (unchanged) was moved to the tf folder.

Unfortunately, I do not have the time and the resources to train and test the new scripts on ImageNet. Anyone would like to take this? Only to check the constistency with the old ones. Thank you!

I have time and resources,but I'm a freshman. I have a lot of detail which I don't understand
