What is this ?

This package provides the following

• ProjectStore for MLflow
  • This is a tracking store for the project:// scheme. It is the same as the FileStore in mlflow package that can be used in File schema except for the following points.
  • Use uuid instead of "incremental int" when naming new MLflow experiment directory.
    • This makes it possible to store the team's experiments/runs in any code repository.
• A "Serverless" experiment record viewer for use in rich IPython environments such as Jupyter-Notebook or Jupyterlab.

Usage

Record your experiments on ProjectStore

import mlflow
mlflow.set_tracking_uri('project://./mlruns') # set storage-uri for tracking
experiment_id = mlflow.create_experiment('sample')

with mlflow.start_run(experiment_id=experiment_id) as run:
    mlflow.log_param("p", 1)
    mlflow.log_param("q", 10)
    mlflow.log_param("r", 100)
    mlflow.log_metric('r2', 0.6)

Explore experiments record on your IPython environments

For "rich" IPython environments such as Jupyter-Notebook.

import flown.api as flown_api
flown_api.list_experiments()

For "poor" IPython environments such as Notebook Preview on PyCharm.

import flown.api as flown_api
flown_api.list_experiments(restricted=True)

Note: Any interactive function is disabled on this restricted mode. Any link does not work.

Run MLflow Server with ProjectStore

Using default directory './mlruns'

$ flown ui

Then you can browse your experiment record via MLflow WEB-UI. ( http://127.0.0.1:5000 )

Using other directory.

$ flown ui --backend-store-uri project://./relational/path/to/dir --default-artifact-root s3://your-bucket/prefix-key

Type flown ui --help for farther information.

How to register to PyPI / for my private memo :)

1. Update version in flown/__version__.py
2. Upload to pypi.

pip install twine
pip install build
cd src
python -m build 
python -m twine upload --repository pypi --verbose dist/*
