<!-- ABOUT THE PROJECT -->
# About the project
### 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.  
### What is SAP HANA?
From [www.sap.com](https://www.sap.com/products/hana.html): 
SAP HANA is a high-performance in-memory database that speeds data-driven, real-time decisions and actions.

<!-- GETTING STARTED -->
# Getting Started

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

## Prerequisites

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](https://www.sap.com/cmp/td/sap-hana-cloud-trial.html) a free trial account  
    * [Setup](https://saphanajourney.com/hana-cloud/learning-article/how-to-create-your-trial-sap-hana-cloud-instance/) an instance  
    * [Enable](https://help.sap.com/viewer/db19c7071e5f4101837e23f06e576495/2020_03_QRC/en-US/502e458a260d4445810e6b9094c5b7e7.html) 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](https://developers.sap.com/group.hxe-install-binary.html) HANA instance there or on your PC (if you have >32 Gb RAM).
      * [Enable](https://www.youtube.com/watch?v=NyEIj76aqFg&list=PLkzo92owKnVy6nOZMFZIZxcvBCoRdshsR&index=19) 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
  ```sh
  pip3 install Cython
  ```

## Installation
There are 2 ways to install the library
* Stable: from pypi (currently the project lives on Test Pypi)
   ```sh
   pip3 install --extra-index-url https://test.pypi.org/simple/ hana_automl
   ```
* Latest: from the repository
   ```sh
   pip3 install https://github.com/dan0nchik/SAP-HANA-AutoML/archive/dev.zip
   ```
  **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  
  ```python
  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")
   ```


<!-- USAGE EXAMPLES -->
# Usage 

## From code
Our library in a few lines of code

Connect to database.
```python
from hana_ml.dataframe import ConnectionContext

cc = ConnectionContext(address='address',
                     user='username',
                     password='password',
                     port=1234)

```
Create AutoML model and fit it.
```python
from hana_automl.automl import AutoML

model = AutoML(cc)
model.fit(
  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
)
```
Predict.
```python
model.predict(
file_path='path to test dataset',
id_column='ID',
verbose=1
)
```

_For more examples, please refer to the [Documentation](https://sap-hana-automl.readthedocs.io/en/latest/index.html)_

## How to run Streamlit client
1. Clone repository: `git clone https://github.com/dan0nchik/SAP-HANA-AutoML.git`
2. Install dependencies: `pip3 install -r requirements.txt`
3. Run GUI: `streamlit run ./web.py`


<!-- ROADMAP -->
# Roadmap

See the [open issues](https://github.com/dan0nchik/SAP-HANA-AutoML/issues) for a list of proposed features (and known issues). Feel free to report any bugs :)



<!-- CONTRIBUTING -->
# Contributing

Any contributions you make are **greatly appreciated** 👏!

1. Fork the Project
2. Create your Feature Branch (`git checkout -b feature/NewFeature`)
3. Install dependencies  
   ```sh
   pip3 install Cython
   ```
    ```sh
   pip3 install -r requirements.txt
   ```
4. Create `credentials.py` file in `tests` directory
    Your files should look like this:  
    ```
    SAP-HANA-AutoML
    │   README.md
    │   all other files   
    │   .....
    |
    └───tests
        │   test files...
        │   credentials.py
      ```

    Copy and paste this piece of code there and replace it with your credentials:
    ```python
    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`)
    ```sh
    pytest
    ```
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
