May 15, 2013

lets have lot of key-pair data. have data in package can imported. there way make modules work dicts, performance , extendibility reasons? example: common/pairs/ ├── buildings.py └── __init__.py import buildings buildings["foo"] == "bar" note: desired result can archived putting declaring buildings in __init__.py compiled every time, not drag , undroppable, , seems ugly. is there way achieve well? there way achieve @ all? not recommend it, can assign dict sys.modules . python doesn't care what's there module object. # buildings.py sys import modules if __name__ != "__main__": modules[__name__] = {'a': 1, 'b': 2, ...}

python - calling dot products and linear algebra operations in Cython? -

May 15, 2013

i'm trying use dot products, matrix inversion , other basic linear algebra operations available in numpy cython. functions numpy.linalg.inv (inversion), numpy.dot (dot product), x.t (transpose of matrix/array). there's large overhead calling numpy.* cython functions , rest of function written in cython, i'd avoid this. if assume users have numpy installed, there way like: #include "numpy/npy_math.h" as extern , , call these functions? or alternatively call blas directly (or whatever numpy calls these core operations)? to give example, imagine have function in cython many things , in end needs make computation involving dot products , matrix inverses: cdef myfunc(...): # ... many things faster python # ... # compute 1 value using dot products , inv # without using # import numpy np # np.* val = gammaln(sum(v)) - sum(gammaln(v)) + dot((v - 1).t, log(x).t) how can done? if there's library implements these in cython alrea
