Uhm I would think that the tf.keras API is a clone of Keras (I mean, Keras was made by a Google Engineer!!)... which came before Pytorch

tf.keras contains a deprecated API that was the original keras as well as a new API that basically is a clone of Pytorch. You can tell the difference because only the new API works nicely with eager mode.

And the torch API has been around for a looooonnng time, as Pytorch is a re-implementation of Torch, which was written in Lua: http://torch.ch/
