NFT Search Engine with Python and Flask

NFT-Search-Engine

In this tutorial, we’ll learn how to transform our command-line based NFT Search Engine from the previous tutorial and turn it into a full-blown web application using Python and Flask.

Dataset

For this tutorial, we will be utilizing a dataset that I manually scraped from the OpenSeas website (a market place where you could purchase NFTs) by downloading a bunch of NFTs profile picture projects.

The downloaded ones are:

1) Bored Apes
2) Cryptopunk, and
3) Alien Frens

USAGE

• git clone https://github.com/Neuraspike/Flask-NFT-Search-Engine

• cd Flask-NFT-Search-Engine

Before running the script, make sure you have all the requirements already installed.

• pip install -r requirements.txt

Now you can:

• Extract features from the database of images: python extract_features.py --dataset ./static/img/ --index ./static/output/features.csv
• Perform the search via localhost:5000: python app.py
• Select an image from the folder directory: static/upload/
