Graph Karaoke Graph

This is the start of a project that will allow you to create a Graph Karaoke Kiosk using python, Neo4j, and youtube. The flask application allows opening a flask browser window allowing to input a song into the machine. Lyrics are fetched from the pylyrics3 python package and stored in Neo4j. The application will search youtube for the song and play it while displaying the lyrics. This app builds the graph of the song using a second browser. Once this is done, it will open a new browser and build up the lyrics to produce the results neo4j graph karaoke results.

This is the first version. When asked for originally recording graph karaoke video we instead build a system which eliminates the data munging requirements of producing a video. Hence this work is a product of laziness, as a result, please use with care. We are not liable for bad singing in any way if you so choose to sing along. ; )

Here is a video demo of our Graph Karaoke in action! The user only enters the name of the artist and song. Everything else is automated.

PS. This work is inspired by Rik Van Bruggen @rvanbruggen

Pre requisites

You’ll need to have the following installed:

Neo4j 3.X
Python  3.6.0 recommended
Flask
setup a python virtual environment

Step 1- Download Python 3.6

https://www.python.org/downloads/release/python-363

Step 2 - Install Python step by step :

Step 3 - Setup virtual python environment

http://python-guide-cn.readthedocs.io/en/latest/dev/virtualenvs.html

Step 4 - Install Python package requirements

/myproject/pip install -r requirements

Step 5 - Setup Neo4j (Your Graph Database)

https://neo4j.com/sandbox-v2/

Open config.py and change the setup with your unique configuration details of your neo4j server IP and credentials.

NEO4J_IP = '198.168.XXX.XXX'
NEO4J_PASSWORD = 'MY-PASSWORD'
NEO4J_PATH = 'C:/Users/<UserName>/PATH/neo4j-enterprise-3.2.0/import/'

print(NEO4J_IP)
print(NEO4J_PASSWORD)
print(NEO4J_PATH)

Import Chrome configuration

Install a chrome plugin for allowing all pages to be iframed

Download latest chromedirver from google and place into a working directory.

Open run_second_open_newbrowser.py and edit the below!

#Please point the app to your local chrome profile!
chrome_options.add_argument("user-data-dir=C:\\Users\<YOURUSERNAME>\AppData\Local\Google\Chrome\\User2 Data")

#Point to the downloaded driver

self.driver = webdriver.Chrome('C:\\Users\\<YOURUSERNAME>\\Downloads\\chromedriver_win32\\chromedriver.exe',
                                       chrome_options=chrome_options)

Run Graph Karaoke

Just run the two below scripts in order, locally using your IDE. This application is designed to be run locally as a kiosk by the way :)

python3 run_first_views.py

python3 run_second_open_newbroswer.py

Things to do

  • ❏ Add more inline code documetation.

  • ❏ Add Twillo SMS capability

Known Issues:

Lyrics are not synchronized with the playing of the song on youtube.
Automation is driven by selenium webdriver. So any key or mouse  movement after the song selection is initialized
might cause unexpected behavior.
