scheme - How to load an extension in Guile 2.0? -

-

i'm trying load graphviz extension guile 2.0. line of scheme code, suggested graphviz's documentation, works in guile 1.8:

(load-extension "/usr/lib/graphviz/guile/libgv_guile.so" "swig_init")

however, fail in guile 2.0 following error:

scheme@(guile-user)> (load-extension "/usr/lib/graphviz/guile/libgv_guile.so" "swig_init")  error: in procedure load-extension: error: in procedure dynamic-link: file: "/usr/lib/graphviz/guile/libgv_guile.so", message: "file not found"  entering new prompt.  type `,bt' backtrace or `,q' continue.

i've tried using following alternative paths well:

/usr/lib/graphviz/guile/libgv_guile libgv_guile

same results. how do that?

the problem distribution's graphviz packages compiled against guile 1.8, , 2 versions of guile not abi compatible.

compiling graphviz linking against guile 2.0 (with guile 2.0's headers) solved it.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
