如何解决ufunc 'square' not supported ……错误

fig = plt.figure()
ax = Axes3D(fig)

X=np.array(Length)
Y=np.array(Viscera)


X,Y=np.meshgrid(X,Y)

R=np.sqrt(X**2+Y**2)
#height value
Z=np.sin(R)

ax.plot_surface(X,Y,Z,rstride=1,cstride=1,cmap=plt.get_cmap('rainbow'))
ax.contourf(X,Y,Z,zdir='z',offset=-2,cmap='rainbow') #等高线图  即下面的部分
ax.set_zlim(-2,2)

改成列表和元组形式都出现一下错误

ufunc 'square' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''
