How to use the floris.tools.sowfa_utilities.SowfaInterface function in floris

# Define a quick function for getting arbitrary points from sowfa
from sklearn import neighbors

def get_points_from_flow_data(x_points,y_points,z_points,flow_data):
    X = np.column_stack([flow_data.x,flow_data.y,flow_data.z])
    n_neighbors = 1
    knn = neighbors.KNeighborsRegressor(n_neighbors)
    y_ = knn.fit(X, flow_data.u)

    # Predict new points
    T = np.column_stack([x_points,y_points,z_points])
    return knn.predict(T)

# Load the SOWFA case in
si = wfct.sowfa_utilities.SowfaInterface('sowfa_example')

# Initialize the FLORIS interface fi
fi = wfct.floris_interface.FlorisInterface("example_input.json")

# Get HH and D
HH = fi.floris.farm.flow_field.turbine_map.turbines[0].hub_height
D = fi.floris.farm.turbines[0].rotor_diameter

wind_speed_mod = 0.3

# Match SOWFA
fi.reinitialize_flow_field(wind_speed=[si.precursor_wind_speed - wind_speed_mod],
