numexpr free download, latest version ✅2.7, Numexpr is a fast numerical expression evaluator for NumPy.
Numexpr is a fast numerical expression evaluator for NumPy that accelerates array-based operations such as “3*a + 4*b” while using significantly less memory than standard Python execution. Built for speed, it streamlines data processing in scientific computing, machine learning preprocessing, and large-scale data analysis.
Its efficient multi-threaded engine automatically uses all available CPU cores, delivering major performance boosts—especially for workloads that are not memory-bounded, including those involving transcendental functions. This makes it ideal for users handling heavy numerical workloads or optimizing performance in data-driven pipelines.
Numexpr also supports Intel’s VML (Vector Math Library), part of the Intel MKL, unlocking even faster execution for transcendental expressions. With optimized vectorized math and low-overhead computation, it’s a powerful solution for anyone needing high-speed numerical evaluation on large arrays.
