I receive a segmentation fault from the following code: from scipy.optimize import * from scipy import * # Fit Mean of A*x to Mean of B---------- #-------------------------------------- def fit(x): d=mean(x*A)-mean(B) return d #-------------------------------------- A=[1,2] B=[3,4] x0=[1] (x,msg)=leastsq(fit,x0) print x Any advice? thanks, djoefish

Please give a more detailed report. What versions of scipy and numpy are you using? And if you can provide a trace-back that is even better. -Travis

I don't see any memory errors running your code with numpy 1.0.dev3230 scipy 0.5.2.dev2235 It produces the correct answer, 2.3333333. Which versions of numpy and scipy are you running, and on which platform? Regards Stéfan
