The Iguazio Data Science platform ("the platform") is a fully integrated and secure data science platform as a service (PaaS), which simplifies development, accelerates performance, facilitates collaboration, and addresses operational challenges. The platform incorporates the following components:
- A data science workbench that includes Jupyter Notebook, integrated analytics engines, and Python packages
- The MLRun open-source MLOps orchestration framework for ML model management with experiments tracking and pipeline automation
- Managed data and machine-learning (ML) services over a scalable Kubernetes cluster
- A real-time serverless functions framework for model serving (Nuclio)
- An extremely fast and secure data layer that supports SQL, NoSQL, time-series databases, files (simple objects), and streaming
- Integration with third-party data sources such as Amazon S3, HDFS, SQL databases, and streaming or messaging protocols
- Real-time dashboards based on Grafana
Data Science Workflow
The platform provides a complete data science workflow in a single ready-to-use platform that includes all the required building blocks for creating data science applications from research to production:
- Collect, explore, and label data from various real-time or offline sources
- Run ML training and validation at scale over multiple CPUs and GPUs
- Deploy models and applications into production with serverless functions
- Log, monitor, and visualize all your data and services
The Tutorial Notebooks
The home directory of the platform's running-user directory (/User/<running user>) contains pre-deployed tutorial Jupyter notebooks with code samples and documentation to assist you in your development — including a demos directory with end-to-end use-case applications (see the next section) and a data-ingestion-and-preparation] directory with documentation and examples for performing data ingestion and preparation tasks.
- To view and run the tutorials from the platform, you first need to create a Jupyter Notebook service.
- The welcome.ipynb notebook and main README.md file provide the same introduction in different formats.
Start out by running the getting-started tutorial to familiarize yourself with the platform and experience firsthand some of its main capabilities.
You can also view the tutorial on GitHub.
End-to-End Use-Case Application and How-To Demos
Iguazio provides full end-to-end use-case application and how-to demos that demonstrate how to use the platform, its MLRun service, and related tools to address data science requirements for different industries and implementations.
These demos are available in the MLRun demos repository.
Use the provided update-demos.sh script to get updated demos from this repository.
By default, the script retrieves the files from the latest release that matches the version of the installed
mlrun package (see Installing and Updating the MLRun Python Package).
The files are copied to the /v3io/users/<username>/demos directory, where
<username> is the name of the running user (
$V3IO_USERNAME) unless you set the
-u|--user flag to another username.
Note: Before running the script, close any open files in the demos directory.

End-to-End Use-Case Application Demos
|News Article Summarization and Keyword Extraction via NLP||
View on GitHub
|Demonstrates how to create an NLP pipeline that will summarize and extract keywords from a news article URL. We will be using state-of-the-art transformer models such as BERT to perform these NLP tasks.|
View on GitHub
|Demonstrates how to use MLRun to create a mask detection app. We'll train a model that classifies an image of a person as wearing a mask or not, and serve it to an HTTP endpoint.|
|Fraud Prevention - Iguazio Feature Store||
View on GitHub
|Demonstrates how to develop a fraud prevention pipeline using the Iguazio feature store. The demo creates a full end to end flow starting with creating feature sets,then deploying them as operational feature sets, then train the models, then deploy it as an online serving function, and then close the loop with model monitoring.|
|How-To: Converting existing ML code to an MLRun project||

Installing and Updating the MLRun Python Package
The demo applications and many of the platform tutorials use MLRun — Iguazio's end-to-end open-source MLOps solution for managing and automating your entire analytics and machine-learning life cycle, from data ingestion through model development to full pipeline deployment in production.
MLRun is available in the platform via a default (pre-deployed) shared platform service (
However, to use MLRun from Python code (such as in the demo and tutorial notebooks), you also need to install the MLRun Python package (
The version of the installed package must match the version of the platform's MLRun service and must be updated whenever the service's version is updated.
The platform provides an
/User data mount.
Use the following command to run this script for the initial package installation (after creating a new Jupyter Notebook service) and whenever the MLRun service is updated; (the command should be run for each Jupyter Notebook service):
Data Ingestion and Preparation
The platform allows storing data in any format. The platform's multi-model data layer and related APIs provide enhanced support for working with NoSQL ("key-value"), time-series, and stream data. Various steps of the data science life cycle (pipeline) might require different tools and frameworks for working with data, especially when it comes to the different mechanisms required during the research and development phase versus the operational production phase. The platform features a wide array of methods for manipulating and managing data, of different formats, in each step of the data life cycle, using a variety of frameworks, tools, and APIs — such as as the following:
- Spark SQL and DataFrames
- Spark Streaming
- Presto SQL queries
- pandas DataFrames
- V3IO Frames Python library
- V3IO SDK
- Web APIs
The Ingesting and Preparing Data tutorial README (data-ingestion-and-preparation/README.ipynb/.md) provides an overview of various methods for collecting, storing, and manipulating data in the platform, and references to sample tutorial notebooks that demonstrate how to use these methods.

Creating Virtual Environments in Jupyter Notebook
A virtual environment is a named, isolated, working copy of Python that maintains its own files, directories, and paths so that you can work with specific versions of libraries or Python itself without affecting other Python projects. Virtual environments make it easy to cleanly separate projects and avoid problems with different dependencies and version requirements across components. See the virtual-env tutorial notebook for step-by-step instructions for using conda to create your own Python virtual environments, which will appear as custom kernels in Jupyter Notebook.
Updating the Tutorial Notebooks
You can use the provided igz-tutorials-get.sh script to get updated platform tutorials from the tutorials GitHub repository. By default, the script retrieves the files from the latest release that matches the current platform version. For details, see the update-tutorials.ipynb notebook.
The v3io Directory
The v3io directory that you see in the file browser of the Jupyter UI displays the contents of the
v3io data mount for browsing the platform data containers.
For information about the platform's data containers and how to reference data in these containers, see platform Data Containers.
The Iguazio support team will be happy to assist with any questions.
