# Microsoft Health Intelligence Machine Learning Toolbox

## Overview

This toolbox aims at providing low-level and high-level building blocks for Machine Learning / AI researchers and
practitioners. It helps to simplify and streamline work on deep learning models for healthcare and life sciences,
by providing tested components (data loaders, pre-processing), deep learning models, and cloud integration tools.

This toolbox is still in very early stages, and presently offers only the cloud integration components. ML components
will be added in the next few weeks.

## Getting started

* Install from `pypi` via `pip`, by running `pip install hi-ml`

## Documentation

The detailed package documentation, with examples and API reference, is on 
[readthedocs](https://hi-ml.readthedocs.io/en/latest/).


## Quick start: Using the Azure layer

Use case: you have a Python script that does something - that could be training a model, or pre-processing some data.
The `hi-ml` package can help easily run that on Azure Machine Learning (AML) services.

Here is an example script that reads images from a folder, resizes and saves them to an output folder:
```python
from pathlib import Path
if __name__ == '__main__':
    input_folder = Path("/tmp/my_dataset")
    output_folder = Path("/tmp/my_output")
    for file in input_folder.glob("*.jpg"):
        contents = read_image(file)
        resized = contents.resize(0.5)
        write_image(output_folder / file.name)
```
Doing that at scale can take a long time. **We'd like to run that script in AzureML, consume the data from a folder in
blob storage, and write the results back to blob storage**.

With the `hi-ml` package, you can turn that script into one that runs on the cloud by adding one function call:

```python
from pathlib import Path
from health.azure.himl import submit_to_azure_if_needed
if __name__ == '__main__':
    current_file = Path(__file__)
    run_info = submit_to_azure_if_needed(compute_cluster_name="preprocess-ds12",
                                         input_datasets=["images123"],
                                         # Omit this line if you don't create an output dataset (for example, in
                                         # model training scripts)
                                         output_datasets=["images123_resized"],
                                         default_datastore="my_datastore")
    # When running in AzureML, run_info.input_datasets and run_info.output_datasets will be populated,
    # and point to the data coming from blob storage. For runs outside AML, the paths will be None.
    # Replace the None with a meaningful path, so that we can still run the script easily outside AML.
    input_dataset = run_info.input_datasets[0] or Path("/tmp/my_dataset")
    output_dataset = run_info.output_datasets[0] or Path("/tmp/my_output")
    files_processed = []
    for file in input_dataset.glob("*.jpg"):
        contents = read_image(file)
        resized = contents.resize(0.5)
        write_image(output_dataset / file.name)
        files_processed.append(file.name)
    # Any other files that you would not consider an "output dataset", like metrics, etc, should be written to
    # a folder "./outputs". Any files written into that folder will later be visible in the AzureML UI.
    # run_info.output_folder already points to the correct folder.
    stats_file = run_info.output_folder / "processed_files.txt"
    stats_file.write_text("\n".join(files_processed))
```

Once these changes are in place, you can submit the script to AzureML by supplying an additional `--azureml` flag
on the commandline, like `python myscript.py --azureml`.

That's it!
