nano_data_scientist_project2's Introduction

Disaster Response Pipeline Project

Instructions:

  1. To prepare the workspace of the project

    • Download the project code from the github repository

    • active your local venv in project root path:

      python3 -m venv venv

    • insstall all requirements

      pip3 install -r requirements.txt

  2. Run the following commands in the project's root directory to set up your database and model.

    • To run ETL pipeline that cleans data and stores in database python data/process_data.py data/disaster_messages.csv data/disaster_categories.csv data/DisasterResponse.db
    • To run ML pipeline that trains classifier and saves python models/train_classifier.py data/DisasterResponse.db models/classifier.pkl

  3. Run the following command in the app's directory to run your web app. python run.py

  4. Go to http://0.0.0.0:3001/
