BabylonJS Lathe Shape Update

Has anyone come across a method to update the shape and/or other options in a lathe mesh? Currently I'm just redrawing them, but every update called on it just creates a new one, and disposing it is not working.

What I want to do is basically just:

this.lathe.shape = pointArray;

But I don't think there is any way to access it or set it.

I have tried this method of disposing and building a new mesh and it doesn't work and is not ideal for what I'm trying to do:

this.lathe.dispose();
this.lathe = BABYLON.MeshBuilder.CreateLathe(...);

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...
