rezAWARE

The README file is useful for projects that are using rezaware platform for AI/ML and augmented BI pipelines. It is designed to integrate data wrangling, mining, and visualization in to a single coherent project. Here we introduce ways for getting started with the platform framework. The WIKI for comprehensive documentation on the rezaware methodology, functional components, and behaviour.

NOTE: instructions and content is specific to Debian distros and was tested on Ubuntu 20.04.

Table of Content

• Starting a new project - starting the rezaware framework
• Test the newly set project - run pytest scripts to ensure rezaware integrity
• Updating rezaware in your project - to pull the latest code from rezaware repo and apply to your project submodule
• Re-configuring an existing project - redoing the folders, init, and app.ini files
• Description of the project artifacts - brief description of the essential framework files and folders

Starting a New Project

1. Create an empty git repository with the a desired project name; e.g., MyNewProj .
   • Presupose that you have git installed and initialized on your computer.
2. Clone your MyNewProj into a desired director location; for example
   • cd ~/all_rez_projects/
   • git clone https://github.com/<my_git_user_name>/MyNewProj.git
3. Move into the newly created project folder
   • cd ~/all_rez_projects/MyNewProj
4. Now clone and initialize rezaware platform as a submodule
   • git submodule add -b main https://github.com/waidyanatha/rezaware.git rezaware
   • git submodule init; will copy the mapping from the .gitmodules file into the local ./.git/config file
5. Navigate into the rezaware folder and run setup to initialize the project with AI/ML functional app classes
   • cd rezaware
   • In the next command run the setup for rezaware separately and the apps separately
     • python3 -m 000_setup --app=rezaware --with_ini_files; it is important to use the _--with_inifiles directive_ flag because it instructs _000setup.py to build the rezaware app and python init.py and app.ini files necessary for the seamless package integration
     • python3 -m 000_setup; at the onset you would not have any wrangler, mining, and visuals code in the respective modules folders; hence, you cannot build the python init.py and app.ini files. Without the _--with_inifiles directive the process will simply generate the app folder structure and default app.cfg file.
   • You have now created your MyNewProj with the rezaware platform framework and can begin to start coding.
   • Note you need to configure the app.cfg in the mining,wrangler,and visuals apps
     • each time you add new module packages; it needs to be added or removed from app.cfg
     • any other parameters, specific to the project must be changed.
6. Change back to the project director
   • cd .. or cd ~/all_rez_projects/MyNewProj
7. Add the submodule and initialize
   • git add .gitmodules rezaware/
   • git init
8. Install dependencies with python poetry.
   • The pyproject.tom file would be created from the previous 000_setup.py step
   • poetry --version will confirm if poetry dependency manager is installed
   • If required, follow the poetry installation docs
   • Activate the lock file with poetry lock
   • Install dependencies with poetry install
   • confirm installation and environment with poetry shell; create a default shell with (rezaware-py3.10)
9. (Optional) Include a README.md file, if not already
   • echo "# Welcome to MyNewProj" >> README.md
10. Add and commit all newly created files and folders in MyNewProj
    • git add .
    • git commit -m "added rezaware submudle and setup project"
11. Push the submodule and new commits to the repo
    • git push origin main
    • Check your github project in the browser; you will see a folder rezaware @ xxxxxxx; where xxxxxxx is the last 7 digits from the rezaware.git repo commit code

Test the new Project

Run pytest by executing the command in your terminal prompt

• pytest

Update rezaware from remote repo

From time to time you will need to update the rezaware submodule, in your project.

1. change your directory to MyNewProj folder
   • cd ~/all_rez_projects/MyNewProj
2. fetch latest changes from rezaware.git repository, and merge them into current MyNewProj branch.
   • git submodule update --remote --merge
3. update the repo in github:
   • git commit -s -am "updating rezaware submodule with latest"
   • git push origin main

Reconfiguring existing project

When you add a new module package into the mining, wrangler, and visuals app folders; as well as defining them in the app.cfg file, the init and app.ini framework files need to be updated. For such simply run the _000setup.py

• cd ~/all_rez_projects/MyNewProj/rezaware navigate into the rezaware folder
• python3 -m 000_setup --with_ini_files will re-configure all the apps
• Alternatively python3 -m 000_setup --app=wrangler,mining will only re-configure the specific apps

About the Post Setup Artifacts

1. Mining - Arificial Intelligence (AI) and Machine Learning (ML) analytical methods
2. Wrangler- for processing data extract, transform, and load automated pipelines
3. Visuals - interactive dashboards with visual analytics for Business Intelligence (BI)
4. utils.py- contains a set of framework functions useful for all apps
5. app.cfg - defines the app specific config section-wise key/value pairs
6. Folders - each of the mining, wrangler, and visuals folders will contain a set of subfolders
   • dags - organizing airflow or other scheduler pipelines scripts
   • data - specific parametric data and tmp files
   • db - database scripts for creating the schema, tables, and initial data
   • logs - log files created by each module package
   • modules - managing the package functional class libraries
   • notebooks - jupyter notebooks for developing and testing pipeline scripts
   • tests - pytest scripts for applying unit & functional tests for any of the packages

Deprecated

1. (Recommended) you may also consider setting up an Anaconda environment with python-3.8.10 to avoid any distutils issues.
   • create a new environment using the requirements.txt file that is in the rezaware folder:
     • conda create --name rezenv python=3.8.10 --file requirements.txt
   • Thereafter, check if all packages, listed in requirements.txt was installed
     • conda list will print a list to stdout
   • Activate your conda environment;
     • e.g. conda activate rezenv
