Was anyone able to use fmin_l_bfgs_b optimizer successfully?
When I run it with the same parameters as the fmin_bfgs example in the tutorial,
I get the error:

xopt = fmin_l_bfgs_b(log_likelihood, x0, fprime=log_likelihood_der)
File "C:\Python23\Lib\site-packages\scipy\optimize\lbfgsb.py", line 174, in fm
in_l_bfgs_bisave, dsave)
error: failed in converting 7th argument `g' of _lbfgsb.setulb to C/Fortran
array


BTW, are there searchable archives of this list somewhere?
