Can tags be used for anything other than versioning in a Package? I was registering a package with non-version tags marking some important development points (e.g. a "naacl2016" tag) and the package manager was not happy about it. If no tags are allowed other than the vX.Y.Z tags, is the

Hi Mose, I messed around with the internals of AutoGrad quite a bit. The latest master runs about twice as fast as v0.0.1 (and quite a bit faster than the original Python autograd package). The current performance is ok in array-heavy code (such as training deep learning models where most of

Hi Mosè, Thanks for the wonderful feedback! AutoGrad has some overhead for recording and differentiating primitive operators. However I think there is room for improvement - the current design has elements of the original Python package, anonymous functions, closures, etc. that are probably not
