Dexie: how to query by date?

I'm trying to build a "logs" table (my goals its to know how much time the app is being used), so I created a function that detects if the user is inactive after a certain period of time.

The table is like this:

dblogs.version(1).stores({
    aLogs: "++id, story_id, user_id, session_start, session_end, words_written"
});

So when the user is active I create a new record on aLogs, example:

0, 1 , 19 , 2021/06/30 10:15:10

the user 19 started typing at 2021/06/30 10:15:10(this goes in session_start) then if the user goes inactive I add the current datetime to session_end

Example:

  0, 1 , 19 , 2021/06/30 10:15:10, 2021/06/30 12:15:48

so basically the user estimated time is the difference between those 2 dates (in this case its 2h 0m 38s)

my goal is to have several of these logs, then run a loop on it and story the amount of seconds the user spent "today"

how do I query this on Dexie?

I have tried await dblogs.aLogs.get({session_start : "2021/06/30"}); but it returns undefined

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...
