How to use numba jit
Did you know?
WebNumba is a just-in-time (JIT) compiler for a mathematically relevant subset of NumPy and Python. It allows you to write fast code without leaving the Python environment. The drawback of Numba is that it can only compile code blocks involving objects and functions that it recognizes. Numba provides several utilities for code generation, but its central feature is the numba.jit() decorator. Using this decorator, you can mark a function for optimization by Numba’s JIT compiler. Various invocation modes trigger differing compilation options and behaviours.
WebStarting with numba version 0.12, it is possible to use numba.jit without providing a type-signature for the function.
