Simple but powerful Automated Machine Learning library for tabular data. It uses efficient in-memory SAP HANA algorithms to automate routine Data Science tasks.


This library is an open-source research project and is not part of any official SAP products.

What's this?

This is a simple but accurate Automated Machine Learning library. Based on SAP HANA powerful in-memory algorithms, it provides high accuracy in multiple machine learning tasks. Our library also uses numerous data preprocessing functions to automate routine data cleaning tasks. So, hana_automl goes through all AutoML steps and makes Data Science work easier.

Getting Started

To get a package up and running, follow these simple steps.


Make sure you have the following:

  1. ✅ Setup SAP HANA (skip this step if you have an instance with PAL enabled).
    There are 2 ways to do that.
    In HANA Cloud:

    • Create a free trial account
    • Setup an instance
    • Enable PAL - Predictive Analysis Library. It is vital to enable it because we use their algorithms.

    In Virtual Machine:

    • Rent a virtual machine in Azure, AWS, Google Cloud, etc.
    • Install HANA instance there or on your PC (if you have >32 Gb RAM).
    • Enable PAL - Predictive Analysis Library. It is vital to enable it because we use their algorithms.
  2. ✅ Installed software

  • Python > 3.6
    Skip this step if python --version returns > 3.6
  • Cython
    pip3 install Cython


There are 2 ways to install the library

  • Stable: from pypi
    pip3 install hana_automl
  • Latest: from the repository
    pip3 install
    Note: latest version may contain bugs, be careful!

After installation

Check that PAL (Predictive Analysis Library) is installed and roles are granted

  • Read docs section about that.
  • If you don't want to read docs, run this code
    from hana_automl.utils.scripts import setup_user
    from hana_ml.dataframe import ConnectionContext
    cc = ConnectionContext(address='address', user='user', password='password', port=39015)
    # replace with credentials of user that will be created or granted a role to run PAL.
    setup_user(connection_context=cc, username='user', password="password")


From code

Our library in a few lines of code

Connect to database.

from hana_ml.dataframe import ConnectionContext

cc = ConnectionContext(address='address',

Create AutoML model and fit it.

from hana_automl.automl import AutoML

model = AutoML(cc)
  file_path='path to training dataset', # it may be HANA table/view, or pandas DataFrame
  steps=10, # number of iterations
  target='target', # column to predict
  time_limit=120 # time limit in seconds


file_path='path to test dataset',

For more examples, please refer to the Documentation

How to run Streamlit client

  1. Clone repository: git clone
  2. Install dependencies: pip3 install -r requirements.txt
  3. Run GUI: streamlit run ./


See the open issues for a list of proposed features (and known issues). Feel free to report any bugs :)


Any contributions you make are greatly appreciated ?!

  1. Fork the Project

  2. Create your Feature Branch (git checkout -b feature/NewFeature)

  3. Install dependencies

    pip3 install Cython
    pip3 install -r requirements.txt
  4. Create file in tests directory
    Your files should look like this:

    │   all other files   
    │   .....
        │   test files...

    Copy and paste this piece of code there and replace it with your credentials:

    host = "host"
    user = "username"
    password = "password"
    port = 39015 # or any port you need
    schema = "your schema"

    Don't worry, this file is in .gitignore, so your credentials won't be seen by anyone.

  5. Make some changes

  6. Write tests that cover your code in tests directory

  7. Run tests (under SAP-HANA-AutoML directory)

  8. Commit your changes (git commit -m 'Add some amazing features')

  9. Push to the branch (git push origin feature/AmazingFeature)

  10. Open a Pull Request
