from pykrige.rk import RegressionKriging

# My data
`x = [...]
y = [...]
z = [...]

# Configure the regression kriging model
RK = RegressionKriging(
    x,
    y,
    z,
    regression_model='linear',  # Or any other regression model I try
    variogram_model='linear',   # Or any other variogram model
    verbose=False
)

I’ve tried different regression and variogram models, but I keep getting this error.

Can someone help me understand why I’m getting this error and how I can fix it?
