Digging into the module and how scipy expects data, it looks like another issue could be having duplicate data values for a parameter based on the interpolation kind to use. Linear might be ok with duplicates but quadratic and cubic would not.

Would there be any value in modifying the function to turn the networks that are duplicates of a parameter value and substituting the mean_s of that NetworkSet to prevent duplicate parameters being used in line 1041 of networkSet.py? Or perhaps even omitting extra networks after the first one with a warning message?

Other item is that scipy.interp1d's parameter of kind can take an int instead of a string that could be good to add to the function snippet.
