[SciPy-User] optimize.fmin_cobyla giving nan to objective function
Mon Aug 1 17:06:37 CDT 2011
The code depends on scikit-learn. I'll post the issue there if you think the
problem is related to that module. My thinking is that fmin_cobyla shouldn't
be feeding nan to the objective function.
The code that causes the exception is gp_error.py . I made a change to one
of the functions in scikit-learn, so I just included that file too. Just
keep both files in the same directory.
Thanks for the help.
