trying to to solve the problem of error reporting after interpolation

[Tony-lxl]

Hi,
I'm very interested in your open source code, and attempts to reconstruct, but when I changed the input of the example, I met some error below (multiple sets of data were tried, just part of them were wrong ), I tried to change the border of the minimum optimization problem, but useless. I'm confused, what is the problem of this error? data or the interpolation value?

//..
error: ~.conda\envs\miplib\lib\site-packages\scipy\interpolate\interpolate.py in _check_bounds(self, x_new)
689 "range.")
690 if self.bounds_error and above_bounds.any():
--> 691 raise ValueError("A value in x_new is above the interpolation "
692 "range.")
693

ValueError: A value in x_new is above the interpolation range.
