Updated: Hashtag combination, Starting post

About

This is used to scrape images / videos from Instagam by using chrome driver.

By setting those parameters, you can easily scrape either images or videos or both as well as select your designated path to save them.

It will automatically create folders in a location where you stated in 'save_to_path'. Those folders are named by each username and hashtag.

Before scraping, you will be informed to login your IG account in order to smoothen the scraping process. Don't worry, it wouldn't store your username and password.

Please follow the instructions below to install chrome driver on Colab

!apt install chromium-chromedriver
!cp /usr/lib/chromium-browser/chromedriver /usr/bin
!apt-get update
set chromedriver_path = 'chromedriver'
set chrome_headless = True

Install

pip install igpicker

Upgrade

pip install igpicker --upgrade

Library used

selenium, bs4, time, getpass, IPython, urllib, os, re, tqdm, wget, ssl

Reminder

Sometimes it may not run properly after an intensive scraping. Please wait for a while and start your scraping journey again.

Limitations

• Only allows scraping either by 'username' or 'hashtag' at the same time (but you can easily change 'target_is_hashtag' parameter after finishing your first scraping)
• Only allows chromedriver
• Only allows to set the total number of posts you want

Possible function that can be created in the future

Store each post's information (e.g. like, post time, post location, post description, users' number of followers, etc.) into dataframes, or even consolidate them into databases. Therefore, they can be used to do descriptive analysis, train up machine learning models or build up a recommendation system.

Import Library

from igpicker import IGpicker

Example 1 (Normal flow):

igpicker = IGpicker(target = ['hkfoodtalk', 'sportscenter'], target_is_hashtag = False, chromedriver_path= './chromedriver',
         save_to_path = './', chromedriver_autoquit = False,
         chrome_headless= True, save_img=True, save_video=False, enable_gpu = False, 
         ipython_display_image = True)

chrome_driver = igpicker.login()

all_target = igpicker.scraper(chrome_driver = chrome_driver, num_post = 10, start_from = 1)

igpicker.close_driver(chrome_driver) #manually close if 'chromedriver_autoquit' is False

Example 2 (Hashtag Combination):

igpicker = IGpicker(target = ['pizza'], target_is_hashtag = True, chromedriver_path= 'chromedriver',
       save_to_path = './', chromedriver_autoquit = False,
       chrome_headless= True, save_img=True, save_video=True, enable_gpu = False, 
       ipython_display_image = False)

chrome_driver = igpicker.login()

all_target = igpicker.scraper(chrome_driver = chrome_driver, num_post = 10, start_from = 10, hashtag_combination= ['cheesy', 'cheese'])

Example 3 (Change attributes):

igpicker.save_to_path = '../' #change path

igpicker.target = ['burger', 'hkmusic','pasta'] #change target

igpicker.target_is_hashtag = True #is it "hashtag" page?

igpicker.save_video = True

igpicker.save_img = True

all_target = igpicker.scraper(chrome_driver = chrome_driver, num_post = 10) 

You can run 'scraper' again after you change the parameters if you haven't closed the chrome driver.
