WebThe above results show that the execution is largely dominated by dot products operations (delegated to blas). Hence there is probably no huge gain to expect by rewriting this code in Cython or C/C++: in this case out of the 1.7s total execution time, almost 0.7s are spent in compiled code we can consider optimal.
Webhello world with Cython We can compile Cython code in two ways: 1 using distutils to build an extension of Python; 2 run the cython command-line utility to make a .c file and then compile this file. We illustrate the two ways with a simple say_hello method. Cython code has the extension.pyx.
