How to catch event: re-initialise search in Algolia Instantsearch?

I am using Algolia and the Instantsearch library in a Vue project, to search for items. The user has the option to check each item (with a simple checkbox). Checking at least one item makes a toolbar visible, with a selection of actions to be applied on the selected batch of items in the search results. When an search result item is checked, it fires a Vue method that pushes the item to a Vuex array called "selectedItems". In order not to lose this selection with pagination, I have gone for the infinite hits widget. Thus all results remain on the same page. Until here things work fine. My problem is that when the user clicks on the cross in the searchbox to reinitialise the search, then the items are not checked anymore, but obviously they remain within the "selectedItems" array in Vuex. How can I capture the event of the search re-initialising? If I can catch this event, I can then empty the "selectedItems" array so that it remains in sync with the search results. I have only found this resource that presents events like click, conversion, view: https://www.algolia.com/doc/guides/building-search-ui/going-further/send-insights-events/js/ But nothing about other events like re-initialize search. Thanks for any help!

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...
