[SciPy-User] curve_fit error: Optional parameters not found...
Tue Jun 8 11:36:34 CDT 2010
I downloaded scipy 0.8b1 yesterday; I was excited to try out the new
curve_fit function. Today I have been playing with it and some of the
time it works. Other times I get the error:
RuntimeError: Optimal parameters not found: Both actual and predicted
relative reductions in the sum of squares
are at most 0.000000 and the relative error between two consecutive
iterates is at
I know this has been discussed before (see
but apparently has not been fixed.
Can someone explain why I get this error and how I can avoid it?
