jQuery input picker plugin filter results is not getting to normal after deleting a value from input

I have this php code in items_select.php file

<?php
require_once '../init.php';

    $data = [];
    $q = ((isset($_GET['q']) && $_GET['q'] != '')?sanitize($_GET['q']):'');
    $item_select = $db->query("SELECT * FROM products WHERE itemNo LIKE '$q%' OR title LIKE '$q%'");
    while($item = mysqli_fetch_assoc($item_select)){
    $data[] = $item;
    }
    echo json_encode($data);
    ?>

and in invoice.php I have the jQuery/javascript code

<script>
 $(document).ready(function () {
   $('input#items').inputpicker({
  url: 'parsers/items_select.php',
  fields:['itemNo','title'],
  fieldText:'title',
  fieldValue:'id',
  headShow: true,
  filterOpen: true,
  autoOpen: true
});
   });
 </script>

Now everything is working fine except, when I type/search/filter in the input a text or a value that is available in the options and I didn't select it, I just deleted it in the input, the search/filter results are not going back to normal which is showing every option. This is after I type in the input and delete it enter image description here

This is after I reload the page, I have 2 results already enter image description here

and btw, this only happens when using ajax call/JSON - Remote Search

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...

Sorting large arrays of big numeric stings

I was solving bigSorting() problem from hackerrank: Consider an array of numeric strings where each string is a positive number with anywhere from to digits. Sort the array's elements in non-decreasing, or ascending order of their integer values and return the sorted array. I know it works as follows: def bigSorting(unsorted): return sorted(unsorted, key=int) But I didnt guess this approach earlier. Initially I tried below: def bigSorting(unsorted): int_unsorted = [int(i) for i in unsorted] int_sorted = sorted(int_unsorted) return [str(i) for i in int_sorted] However, for some of the test cases, it was showing time limit exceeded. Why is it so? PS: I dont know exactly what those test cases were as hacker rank does not reveal all test cases. source https://stackoverflow.com/questions/73007397/sorting-large-arrays-of-big-numeric-stings
