It's like a tree, all the curves go from the root to all the branches. When I do this: for curve in curves: x = curve[:, 0] y = curve[:, 1] z = curve[:, 2] tck, u = splprep([x,y,z], s=0) # scipy.interpolate.splprep unew = np.linspace(0, 1, 100) out = splev(unew, tck) ax.plot(out[0], out[1], out[2], label=f'B-spline Curve {idx+1}') Result: splprep return ValueError: Invalid inputs. I know this is an error that occurs when the splprep function encounters points where the inputs are repeated (it's ok to run splprep with a different curve alone), but the number of curves is unknown and I need 'for' to control the number of executions. how to fix it? ty!
