It's amazing to watch Pytorch and TF slowly converging and offering more or less the same capabilities. TF started in graph mode and are now adding eager mode. Pytorch started with eager mode (prototyping) and are now moving to graph mode (production). TF evolved from Google's production environment so it comes as no surprise that it was geared for production first deployments. Pytorch evolved from researchers which explains how it was tailor made for tinkering and prototyping. Good to see the two converging. I am guessing a year from now there won't be any marked difference between the two.
