scipy UnivariateSpline Nan 값 반환

Question

UnivariateSpline 작동에 문제가있어 그 이유를 이해할 수 없습니다. 여기 내 코드

x = gg 
y = AA 
order = np.argsort(x) 
s = UnivariateSpline(x[order], y[order],s=2) 
xs =np.linspace(x.min(), x.max(),1000) 
ys = s(xs) 
print ys, xs 
plt.plot(x, y, 'kx') 
plt.plot(xs, ys) 
plt.show() 

나는 x가 늘어나도록 주문했지만 나는 인쇄 할 때 단지 Nan을 생산했는데, 왜 그런가요? 내 데이터도 포함 시켰습니다. X = [0.87 0.87 1.03 1.11 1.93 1.47 0.86 1.11 1.11 0.87 1.6 1.49 1.69 1.69 1.45 1.27 1.44 1.02 1.55 1 0.89 1.15 0.95 1.35 1.01 0.94 1.33 1.06 1.02 1.69 1.3 0.95 1.44 1.73 1.35 1.06 0.96 0.95 0.88

Answer 1

오류 매개 변수들 = 2 (노트의 수)에 있었다 - 그것은 매우 작다 당신의 데이터. 예를 들어 s = 237에서는 작동하지만 236에서는 작동하지 않습니다. 관측 수와 평활 스플라인의 차수보다 크거나 같아야한다는 것을 알고 있습니다.
