WebComputational graphs are a way of expressing and evaluating a mathematical expression. For example, here is a simple mathematical equation −. p = x + y. We can draw a computational graph of the above equation as follows. The above computational graph has an addition node (node with "+" sign) with two input variables x and y and one output q. WebDec 15, 2024 · Numba and Cython. These libraries provide best execution for code (and in fact some tensor computation libraries, such as Theano, make good use them), but like NumPy and SciPy, they do not actually manage the computational graph itself.
