Tutorial #1 - Rhino Health Federated Computing Platform “Hello World” - Basic Usage

Welcome to the Rhino Health Federated Computing Platform!

This document will guide you through the process of setting up a new project on the Rhino Health Federated Computing Platform (FCP). By following the step-by-step instructions in this document, you will learn how to:

  1. Set up a new project
  2. Prepare data, import it as a Dataset, and explore data metrics.
  3. Containerize your code and run it using our distributed computing platform.
  4. Produce visualizations of the results and create a report within the project.

We are excited to see what you will do with the platform, so let’s get started!

 

Step 1: Getting Started

Important Concepts

  • Container: A container is a lightweight and portable software package that encapsulates an application, its dependencies, and its runtime environment. Containers provide a consistent and isolated environment for applications to run, ensuring that they can run consistently across different computing environments. They offer a standardized way to package, deploy, and manage software applications, making it easier to build, ship, and scale applications across different platforms and infrastructures.
    • Why is this important? In many cases, you will need to build a container to execute code on the FCP.
  • Container Image: A container image is a standalone, executable package that includes everything needed to run a piece of software within a container. It contains the application code, runtime environment, libraries, and dependencies required for the application to function properly. Container images are typically built from a base image and can be easily shared, replicated, and deployed across different containerization platforms, allowing for consistent and reproducible application deployments.
    • Why is this important? Container images are what the FCP will execute in order to run your code on your FCP client or remote FCP clients.
  • Docker: Docker is an open-source platform that enables developers to automate the deployment and management of applications within containers. It provides a simple and efficient way to package applications and their dependencies into portable container images. Docker allows for easy and consistent deployment across different environments, ensuring that applications run reliably and consistently regardless of the underlying infrastructure. It has become a widely adopted tool in the software development industry, simplifying application deployment and promoting scalability and flexibility.
    • Why is this important? The FCP uses Docker to help build your containers in your development environment and then run your containers locally, on your FCP client, or other remote FCP clients
  • Amazon Elastic Container Registry (ECR): ECR is a fully managed container registry service provided by Amazon Web Services (AWS). It allows users to store, manage, and deploy container images, making it easier to run containerized applications on AWS. It provides secure and scalable storage for Docker container images and supports private repositories, access control, and image lifecycle management. Developers and organizations can use Amazon ECR to build, store, and share container images to streamline their container-based workflows.
    • Why is this important? The ECR is where you will push your container images to be run within the FCP.
  • Secure File Transfer Protocol (SFTP): SFTP is a network protocol that provides a secure and encrypted method for transferring files between remote systems. SFTP is commonly used as a secure alternative to FTP (File Transfer Protocol) and allows for secure file transfers over SSH (Secure Shell) connections. It ensures data confidentiality and integrity during file transfers, making it suitable for secure file exchange and remote file management.
    • Why is this important? SFTP will be used to move data from your local computer to your FCP client to be imported by the system for exploitation by your containerized code.
  • Data Schema: A Data Schema is a structure or blueprint that defines the organization, format, and relationships of data within a database or data system. It defines the rules and constraints for how data is organized and represented, including the data types, fields, and their relationships. A Data Schema provides a standardized framework for data storage, retrieval, and manipulation, ensuring the consistency and integrity of the data.
    • Why is this important? Data Schemas are used to describe the structure and format of the data you will import into your FCP client as Datasets.

Configuring your Environment

To configure your environment, please follow the steps on this page. Once you have completed those steps, please return here and continue the tutorial.

 

Tutorial 1: Project Resources

Click here to access the GitHub repository that holds a whole host of resources that will be helpful on your journey with the Rhino FCP.  It also hosts all the external files you will need for this tutorial. Download or clone the repository on your local computer. For this tutorial, you will be using the resources inside the user-resources/tutorials/tutorial_1/ folder

This folder includes:

  • containers/ - This folder contains all the containers that you will push to your ECR repository to be used within the FCP during this tutorial.
  • data/ - This folder contains all the data that will be used in this tutorial.  The folder is structured in a way that will become more familiar to you as you become more comfortable using various parts of the system, such as creating custom containers.
    • input/ - This folder is part of the system's structure as you utilize the FCP features mentioned above. It contains the input data for the tutorial.
      • dataset.csv - This file defines the dataset you will use as input for this project. Each row in this file represents a case (meaning a study or patient). For each case, there is a DICOM series UID, which is similar to a file path, and the related metadata as described in the Data Schema.
      • dicom_data/ - This folder contains the DICOM imaging files, specifically chest X-ray (CXR) images, referenced in the dataset.csv file. When using files as input for your project, it is best practice to keep the files in a dedicated folder separate from the dataset.csv file.
  • notebooks/ - This folder contains the notebooks you will utilize within the tutorial.

Another important directory is the user-resources/rhino-utils/ folder.  This folder contains several utility scripts the Rhino Health team has created to help simplify the process of pushing your containers to the platform, testing your containers locally, and simulating training and inference in a local simulated FL environment.  A subset of these scripts will be used in both Step 5: Running Python Code with Custom Dependencies via the FCP UI and Step 6: Running Federated Training with NVFlare on the FCP UI

 

Step 2: Preparing Your Data

For your data to be available to the FCP, you will first need to transfer the data located within the data/ folder to be able to utilize it within the FCP UI.  If you are new to using SFTP and would like to learn more, please refer to the following support article: How can I move data from my local environment to my Rhino Health client using SFTP?

For this tutorial, you are going to move the following two resources from your local machine to your Rhino Health client:

  1. user-resources/tutorials/tutorial_1/data/input/dataset.csv
  2. user-resources/tutorials/tutorial_1/data/input/dicom_data/

Connecting to your SFTP Server for MacOS, Linux & Windows 10+

  1. Open a terminal or command prompt on your respective operating system, navigate to the folder user-resources/tutorials/tutorial_1/data/input/.  
  2. Connect to your client via SFTP using the following command:
    sftp rhinosftp@RHINO_CLIENT_IP_ADDRESS
  3. Copy the dataset.csv and dicom_data/ files from your local machine into a new folder you create on your Rhino Health client by running the commands below: 
    sftp> mkdir tutorial_1
    sftp> cd tutorial_1
    sftp> put dataset.csv
    sftp> put -r dicom_data/
    sftp> exit

Other Operating Systems

  1. If you have downloaded and configured your SFTP client, skip to the next step. Otherwise, please follow steps 1 and 2 outlined in the following support article under the heading Connecting to your Rhino Health Client via SFTP from Other Operating Systems
  2. Open your SFTP client and connect to your Rhino Client
  3. Using the STFP client to upload your data:
    • On the local machine file system panel, navigate to the folder user-resources/tutorials/tutorial_1/data/input/.
    • On your Rhino Health client file system panel, create a new folder called tutorial_1 and navigate inside of it
  4. Drag the dataset.csv and dicom_data/ files from your local machine file system panel to the Rhino Health client file system panel in order to upload them to your Rhino Health client.

Wait until your files have successfully been uploaded to the Rhino Health client before proceeding to the next step.

 

Step 3: Set Up Your Project on the FCP UI

  6. To review the output of your Code Run, click on the link entitled 1 Dataset under the Output Datasets heading within the first row of the My First Code card.  This link will take you back to the Datasets page, but now on the Analytics tab.  There you will see summary statistics about your newly created Dataset, Site 1 Dataset_addBMI, produced by the latest run of My First Code.
    • A few things of note on the Dataset analytics page:
      • The new field, BMI, is present and has been calculated using the code you provided during the creation of My First Code.
      • The table under the Data Completeness heading shows that the new field, BMI, has a comparatively low data completeness score, only 64%.  This is because it was created using other fields with missing values.

 

Step 5: Running Python Code with Custom Dependencies via the FCP UI

After discovering new insights about the output Dataset in Step 4: Running Simple Python code via the FCP UI, you would like to improve your data completeness metric by adding a preliminary data imputation step. Additionally, you would like to convert the DICOM CXR images into JPEG versions. As data preparation becomes more and more complex it is often better to collect all the steps in a single script that can be run on the platform, rather than perform a series of smaller steps.

We have provided such a script in the user-resources/tutorials/tutorial_1/containers/data-prep folder named dataprep_gc.py This script has a few additional dependencies which are included in the requirements.txt file, go ahead and take a look now.

In order to be able to run this code on the FCP, you will need to include some additional dependencies in your Python Code by following the instructions below:

 

Create a New Data Schema Version that Includes your New Output Schema Fields

  1. Return to the FCP to create another new version of the original Site 1 Dataset schema.  This new Data Schema will serve as the output of your newly created container.  You will do this by repeating Steps 1-6 in Step 4: Running Simple Python Code via the FCP UI.
  2. Fill in the following inputs within the new Schema Field column:
    NOTE: Schema Field values are case-sensitive and must match what is in your code.

  2. Fill in the following fields within the new modal window:
    1. Training Datasets: Site 1 Dataset_complete (v0)
    2. Validation Datasets: Site 1 Dataset_complete(v0)
      • Note: In a real-world scenario you would not select the same Datasets for both training and validation, rather you would split the Datasets into training and validation Datasets first
    3. Output Dataset Name Suffix: _results
    4. Configuration: Do not modify.
    5. Additional Parameters: Do not modify.
  3. Once you have completed entering all the details of your Code Run, click the Run Training button to send your code to be run on your Rhino Health client.
    • Training should take between 10-30 minutes to complete (depending on your Rhino Health client’s hardware) - The training is only performing a single epoch, so model performance will likely be less than stellar
    • Once training has been completed, the system will automatically run inference with your validation Dataset and your newly trained model to produce a new output Dataset with the results of the validation.
  4. After the training and validation steps have successfully completed, you should have a new Dataset within the Datasets page entitled Site 1 Dataset_complete_results. Your Datasets page should now look similar to the screenshot below:
    Step_7.1.png

Step 7: Producing Visualizations of Your Code Run with the Rhino SDK

In this section of the tutorial, you will create a report to visualize the output of your NVFlare Code's Inference results.  If you are interested in learning more about the Rhino SDK, please follow one of the links to the Rhino SDK section of our User Guides.

 

  1. If you do not have Python installed with your development environment, please download and install Python here: Python
  2. If you do not have Jupyter Notebook installed within your development environment, please follow the steps outlined here: Jupyter Notebook Installation
  3. Using your terminal or command prompt, navigate to your user-resources/tutorials/tutorial_1/notebooks folder.
  4. Run the following command to start the Jupyter Notebook, Tutorial 1 - Results Analysis Notebook.ipynb: 
    jupyter notebook "Tutorial 1 - Results Analysis Notebook.ipynb"
  5. Follow the step-by-step tutorial for producing Code Run visualizations using the Rhino SDK by running each of the cells contained within the notebook.
  6. Once you have completed running the entire notebook, switch back over to the FCP.  Navigate to the Code Runs page, clicking the first row labeled V, for validation, within the Prediction Model card.
  7. You will be taken to a new page with two tabs, Report, and Logs. Through the previous steps, we have populated the Report tab. You should now see various charts and your Reports tab within the Code Runs page should now look similar to the screenshot below:Step_7.2.png

 

Congratulations on completing your first tutorial on the Rhino Health FCP!

You should now have a good understanding of:

  1. How to access the FCP and locate your credentials from your profile page
  2. How to create a new project
  3. What a Data Schema is and how to create a new Data Schema
  4. How to move data from your local development environment to your FCP client and then import it as a new Dataset
  5. How to create several different Code Objects (Python Code, Generalized Compute & NVFlare) and run them
  6. How to use the Rhino SDK to create custom reports for visualizing the output of Code Runs

 

Things to try next

  • Adjust the code to produce different results:
    • Change the units for Height and/or Weight
    • Extract new fields from the data
  • Check out the tabular viewer’s advanced features:
    • The tabular viewer (accessible by clicking on a Dataset you have access to, then clicking on the Data tab) includes a few advanced features, such as a fully functional DICOM viewer with annotation capabilities, an auto-generated editable __Notes__ column you can use to append free-text notes to each case, and a viewer for standard image formats such as .jpg and .png.
      You can read about these features in the Rhino Health Federated Computing Platform User Manual and test them in your Hello World project.
  • Try to break things, for example:
    • Mismatches between the Data Schema and the data in the dataset.csv file will produce validation errors when attempting to import the Dataset. We recommend you try altering the Dataset and Data Schema to see what happens.
