things to do

Even if Google Colab is running the program, if you do not touch anything, the program will stop after 90 minutes. As a countermeasure against this session expiration, How to use the add-on of Google Chrome and how to execute the script was introduced, but since the add-on did not work, I click the screen regularly in the Python program I wrote a simple program of the primitive method, so I will introduce it.

How to do

1. Install the pyautogui module

Use the pyautogui module to click on the screen. Install normally using pip. pip install pyautogui 

2. Run Google Colaboratory

Let the program run in Colab as usual. Any browser is OK.

3. Run a Python program

Run the following program from the terminal or editor. For the time being, it is named for_colab.py, but you can freely name it, save it, and execute it.

`for_colab.py`


#! python3
# -*- coding: utf-8 -*-

#Continue to use colab

import time
import pyautogui

print()
print('''Move the mouse cursor slightly left or right every 10 minutes and click.
It will end in 12 hours. Ctrl to stop in the middle+Press c.
''')

try:
    dir = -10
    counter = 0

    while counter < 72:
        time.sleep(600)
        pyautogui.moveRel(dir, 0)
        dir = - dir

        pyautogui.click()
        counter += 1
        # print('counter:', counter)  #Comment out if you want to output when clicked

    print('Stop: 12 hours have passed')


except KeyboardInterrupt:
    print('Stop: Ctrl+End with c')

The program is very simple, wait 10 minutes in time sleep, then move the pointer slightly to the right (or left) and click. After doing it 72 times (= 12 hours), it will end.

4. Return to google colab

Go back to colab, where you started the program earlier, and check that the program is running. Create some blank cells near the end of the colab program and place the pointer in that location. that's all.

Notes

"For_colab.py" is clicked on a regular basis, so it's important where you put the pointer. Since it repeats left and right movements, it will not move in a completely different direction, but be careful where you put the pointer at the end so that colab does not scroll and click unexpected places. ..
Since it is a different program from colab, "for_colab.py" will not stop even after the calculation of colab is completed. When the calculation of colab is finished, stop "for_colab.py" with ctrl -C. I forgot to stop it, and when I thought that the behavior of the computer had changed, "for_colab.py" was running in the back ...
Click every 10 minutes, but before that, set the sleep time to more than 10 minutes so that the computer does not sleep.
Since it is a function that you simply click when the time is up, you cannot do other work during operation. Please use it for sleep learning.

The program "for_colab.py" is clicked every 10 minutes, but according to the rules of colab, you can click within 90 minutes, so change the time sleep value to your liking. Also, if you want to make sure that you clicked when you clicked, enable the commented out PRINT statement. It's a simple program, so please change it to make it easier to use.

Google Colaboratory is very useful for machine learning training because you can use the GPU for free. Train your Google teacher while you sleep.
