Fast numerical expression evaluator for NumPy

NumExpr is a Python library that provides a fast numerical expression evaluator for NumPy. It accelerates array operations by avoiding memory allocation for intermediate results, leading to better cache utilization and reduced memory access. It also leverages multi-threading to utilize multiple CPU cores and supports Intel's Math Kernel Library (MKL) for further performance gains, especially with transcendental functions. The current version is 2.14.1, and it maintains a regular release cadence.
