numpy.multiply — NumPy v1.21 Manual

 · numpy.multiply ¶. numpy.multiply. ¶. Multiply arguments element-wise. Input arrays to be multiplied. If x1.shape = x2.shape they must be broadcastable to a common shape (which becomes the shape of the output). A location into which the result is stored. If provided it must have a shape that the inputs broadcast to.

numpy.clip — NumPy v1.21 Manual

 · numpy.clip¶ numpy. clip (a a_min a_max out = None kwargs) source ¶ Clip (limit) the values in an array. Given an interval values outside the interval are clipped to the interval edges. For example if an interval of 0 1 is specified values smaller than 0 become 0 and values larger than 1 become 1.. Equivalent to but faster than np.minimum(a_max np.maximum(a a_min)).

Numba A High Performance Python Compiler

 · Numba is designed to be used with NumPy arrays and functions. Numba generates specialized code for different array data types and layouts to optimize performance. Special decorators can create universal functions that broadcast over NumPy arrays just like NumPy functions do. Numba also works great with Jupyter notebooks for interactive

 · Scikit-Optimize. Scikit-Optimize or skopt is a simple and efficient library to minimize (very) expensive and noisy black-box functions.It implements several methods for sequential model-based optimization. skopt aims to be accessible and easy to use in many contexts.. The library is built on top of NumPy SciPy and Scikit-Learn.

Parallel Programming with numpy and scipy — SciPy

 · For function f() which does not release the GIL threading actually performs worse than serial code presumably due to the overhead of context switching.However using 2 processes does provide a significant speedup. For function g() which uses numpy and releases the GIL both threads and processes provide a significant speed up although multiprocesses is slightly faster.
