Stock calculation to be done by given date

Stock Calculation to be start from given date

My Sql query is sum stock values for date wise and I stored in value variable.

let value = [
  { place: 'Bangalore', production:16, stock: -3, date: '2021-06-26' },
  { place: 'Bangalore', production:2.5, stock: 13, date: '2021-06-27' },
  { place: 'Bangalore', production:3, stock: 15.5, date: '2021-06-28' },
  { place: 'Bangalore', production:5.5, stock: 18.5, date: '2021-06-29' },
  { place: 'Bangalore', production:4, stock: 24, date: '2021-06-30' },
  { place: 'Bangalore', production:7, stock: 28, date: '2021-07-09' },
  { place: 'Bangalore', production:9, stock: 35, date: '2021-07-10' }
]

I want accumulation of previous day stock+production=today stock. Its working as expected below script. But I have to calculate if middle of date production value change.

value.reduce((acc, cur) => {
   const newArr = acc + cur.stock;
   cur.stock = acc;
   return newArr;
 }, 0);
console.log("value::::",value)

If I update any of the production value in middle of date it has to calculate stock from that date only.

eg expected results: Suppose If edit 2021-06-29 production:5

outcome:

 0: {place: "Bangalore", production: 16, stock: -3, date: "2021-06-26"}
1: {place: "Bangalore", production: 2.5, stock: 13, date: "2021-06-27"}
2: {place: "Bangalore", production: 3, stock: 15.5, date: "2021-06-28"}
3: {place: "Bangalore", production: 6.5, stock: 18.5, date: "2021-06-29"}
4: {place: "Bangalore", production: 4, stock: 25, date: "2021-06-30"}
5: {place: "Bangalore", production: 7, stock: 29, date: "2021-07-09"}
6: {place: "Bangalore", production: 9, stock: 36, date: "2021-07-10"}

Kindly suggest your ideas. Its greatly appreciated

let value = [
  { place: 'Bangalore', production:16, stock: -3, date: '2021-06-26' },
  { place: 'Bangalore', production:2.5, stock: 13, date: '2021-06-27' },
  { place: 'Bangalore', production:3, stock: 15.5, date: '2021-06-28' },
  { place: 'Bangalore', production:5.5, stock: 18.5, date: '2021-06-29' },
  { place: 'Bangalore', production:4, stock: 24, date: '2021-06-30' },
  { place: 'Bangalore', production:7, stock: 28, date: '2021-07-09' },
  { place: 'Bangalore', production:9, stock: 35, date: '2021-07-10' }
]


value.reduce((acc, cur) => {
    const newArr = acc + cur.stock;
    cur.stock = acc;
    return newArr;
  }, 0);
console.log("value::::",value)

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...
