Unless you have already invested a lot of time into learning (and building on top of) TF, I would advise to pick up PyTorch. It’s much easier to learn and use (imperative!), and has higher performance on common workloads.
On the positive side with PyTorch you don’t need nearly as much documentation as you would with TF. TF in general feels like it’s fighting you every step of the way. There’s a lot of cognitive overhead. Not so with PyTorch. Everything is straightforward, and can be run/examined in ipython.
