Hi everyone, NumExpr 2.8.0 is released. This is mostly a version bump. We now support Python 3.10 and support for 2.7 and 3.5 has been discontinued. Project documentation is available at: http://numexpr.readthedocs.io/ Changes from 2.7.3 to 2.8.0 --------------------------- * Wheels for Python 3.10 are now provided. * Support for Python 2.7 and 3.5 has been discontinued. * All residual support for Python 2.X syntax has been removed, and therefore the setup build no longer makes calls to the `2to3` script. The `setup.py` has been refactored to be more modern. * The examples on how to link into Intel VML/MKL/oneAPI now use the dynamic library. What's Numexpr? --------------- Numexpr is a fast numerical expression evaluator for NumPy. With it, expressions that operate on arrays (like "3*a+4*b") are accelerated and use less memory than doing the same calculation in Python. It has multi-threaded capabilities, as well as support for Intel's MKL (Math Kernel Library), which allows an extremely fast evaluation of transcendental functions (sin, cos, tan, exp, log...) while squeezing the last drop of performance out of your multi-core processors. Look here for a some benchmarks of numexpr using MKL: https://github.com/pydata/numexpr/wiki/NumexprMKL Its only dependency is NumPy (MKL is optional), so it works well as an easy-to-deploy, easy-to-use, computational engine for projects that don't want to adopt other solutions requiring more heavy dependencies. Where I can find Numexpr? ------------------------- The project is hosted at GitHub in: https://github.com/pydata/numexpr You can get the packages from PyPI as well (but not for RC releases): http://pypi.python.org/pypi/numexpr Documentation is hosted at: http://numexpr.readthedocs.io/en/latest/ Share your experience --------------------- Let us know of any bugs, suggestions, gripes, kudos, etc. you may have.
