Re: [Numpy-discussion] ANN: NumExpr3 Alpha

Yes, Julian is doing an amazing work on getting rid of temporaries inside NumPy. However, NumExpr still has the advantage of using multi-threading right out of the box, as well as integration with Intel VML. Hopefully these features will eventually arrive to NumPy, but meanwhile there is still

Hi All, Just a side note that at a smaller scale some of the benefits of numexpr are coming to numpy: Julian Taylor has been working on identifying temporary arrays in https://github.com/numpy/numpy/pull/7997. Julian also commented (https://github.com/numpy/numpy/pull/7997#issuecomment-246118772)

Re: [Numpy-discussion] ANN: NumExpr3 Alpha

Hi Juan, A guy on reddit suggested looking at SymPy for just such a thing. I know that Dask also represents its process as a graph. https://www.reddit.com/r/Python/comments/5um04m/numexpr3/ I'll think about it some more but it seems a little abstract still. To a certain extent the NE3 compiler

Hi everyone, Thanks for this. It looks absolutely fantastic. I've been putting off using numexpr but it looks like I don't have a choice anymore. ;) Regarding feature requests, I've always found it off putting that I have to wrap my expressions in a string to speed them up. Has anyone explored

Yay! This looks really exciting. Thanks for all the hard work! Francesc 2017-02-17 12:15 GMT+01:00 Robert McLeod : > Hi everyone, > > I'm pleased to announce that a new branch of NumExpr has been developed > that will hopefully lead to a new major version release in the
