However if we use synaptic transistor hardware, the only allowed weight values might be {0, 0. (it's still underfitting at that point, though). The major difference from Tensorflow is that PyTorch methodology is considered "define-by-run" while Tensorflow is considered "defined-and-run", so on PyTorch you can for instance change your model on run-time, debug easily with any python debugger, while tensorflow has always a graph definition/build.
