Jupyter Notebook Multiprocessing code not working

I am new in python i have Anaconda Pyton 3.9 I was studying about Multiprocessing.

When i try this code

from multiprocessing import Process # gerekli kütüphaneyi çağıracağız.

import time

def subfunc1():
    time.sleep(2)
    print("subfunc1: Baslatildi")
    time.sleep(2)
    print("subfunc1: Sonlandi")
    time.sleep(2)

def subfunc2():
    time.sleep(2)
    print("subfunc2: Baslatildi")
    time.sleep(2)
    print("subfunc2: Sonlandi")
    time.sleep(2)
    
def mainfunc():
    print("mainfunc: Baslatildi")
    pr1 = Process(target=subfunc1)
    pr2 = Process(target=subfunc2)
    pr1.start()
    pr2.start()
    print("mainfunc: Sonlandi")
    
if __name__ == '__main__': # Main kod bloğunun içerisindeyken main fonk çağır!
    mainfunc()

result is

    mainfunc: Baslatildi
    mainfunc: Sonlandi

When i use Visual Code with Python 3.9 i have a virtual and code works! Visual Code uses Anaconda's python 3.9 within a virtual env!

Could you please help me? Whey this code can't work properly in Jupyter Notebook?

Thanks

How to split a rinex file if I need 24 hours data

I am expecting a rinex file with 24 hrs or 1 day data.I Have 48 hrs data in RINEX format. Please help me to solve this issue. source https://stackoverflow.com/questions/75385367/how-to-split-a-rinex-file-if-i-need-24-hours-data

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
