Find the minimum of a 2d interpolation

I'm trying to find the minimum of a 2d interpolation. I"m really stuck on trying to find a way to appropriately pass the data to the optimizer,

here is the code I have so far: 

import scipy
from scipy.interpolate import interp2d
a_ca_energy_interp = interp2d(a, c_a, Energy)

def run_2d_params(params, func):
    a, b = params
    return func(a, b)

scipy.optimize.fmin(run_2d_params, np.array([1.60,6.075]),
                    args=a_ca_energy_interp)

Which throws the error: 

TypeError: can only concatenate tuple (not "interp2d") to tuple

args must be a tuple, even if it is only one argument:

scipy.optimize.fmin(run_2d_params, np.array([1.60,6.075]),
                    args=(a_ca_energy_interp, ))
