python 3.x - Simulating Network flows in NetworkX -

-

i trying simulate network flow problem in networkx each node constrained capacity. need specify demand rates , capacity @ every node (also ensure flows don't exceed capacity). of now, have defined flows edge weights.

is there way in networkx? if so, modules, should using? nice if visualize network simulation. simple code involving 4 or 5 nodes lot.

thanks.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...

i using enumerator values flags: typedef enum { = 0x00, b = 0x01u, // u has no influence, expected c = 0x02u, // u has no influence, expected ... } enum_name; volatile unsigned char* reg = someaddress; *reg |= b; according misra-c:2004 bitwise operations shall not done signed type. unfortunately, compiler iar use signed int (or short or char) underlying type of enums, , option can find relates size, not signedness ("--enum-is-int"). according iar c/c++ development guide arm , pages 169 , 211, can define type of enum s if enable iar language extensions ( -e command-line option, or project > options > c/c++ compiler > language > allow iar extensions in ide). in particular, should define "sentinel" value, make sure compiler chooses correct type. prefers signed types, , uses smallest possible integer type, sentinel should largest positive integer corresponding unsigned integer type can describe. example, typedef enum ...
