python中的SmoothBivariateSpline用户警告错误

Question

我在Python中使用SmoothBivariateSpline插值来处理二维非结构化数据集。 这是我的代码：

import numpy as np
from scipy import interpolate

L = np.loadtxt('Somefile.txt')

P = L[:,0]  # extracting first coloumn (independent variable 1)
H = L[:,1]  # extracting second coloumn (independent variable 2)
T = L[:,2]  # extracting third coloumn (dependent variable)

Spline = interpolate.SmoothBivariateSpline(P, H, T, kx=3, ky=3, s=0)

我收到以下错误：

C:\Python27\lib\site-packages\scipy\interpolate\fitpack2.py:639: UserWarning: ier=2348
warnings.warn(message)

可以告诉我可能出错的地方吗？
