Track your machine learning experiments with LolaML,
never lose any information or forget which parameter yielded which results.
Lola creates a simple JSON representation of the run that contains all the
information you logged.
The JSON can easily be shared to collaborate with friends and colleagues.
Lola strives to be non-magic and simple but configurable.

**Features:**

- a simple logging interface
- a simple JSON representation of the logged data
- works with any machine learning library
- automatically creates an artifact folder for each run
- automatically uploads artifacts to a remote bucket (if you want)
- simple jupyter notebook dashboard (more to come...)

::

    import lolaml as lola

    # Use the run context manager to start/end a run
    with lola.Run(project="mnist", prefix_path="data/experiments") as run:
        # a unique id for the run
        print(run.run_id)
        # store all artifacts (model files, images, etc.) here
        print(run.path)  # -> data/experiments/mnist/<run_id>

        run.log_param("lr", 0.1)
        run.log_param("epochs", 10)

        run.log_tags("WIP", "RNN")

        # Create and train your model...

        run.log_metric("loss", loss, step=1)
        run.log_metric("train_acc", train_acc, step=1)
        run.log_metric("val_acc", val_acc, step=1)

        model.save(os.path.join(run.path, "model.pkl"))

    # After a run there is a lola_run*.json file under run.path.
    # It contails all the information you logged.

After the run there is a JSON file that looks something like this::

    {
        "project": "mnist",
        "run_id": "9a531da0-dc43-4dcc-8968-77fd480ff7ee",

            "cwd": "some/where",
            "__file__": "somefile.py",
            "argv": [],
        }
    }


Lola can automatically upload all artifacts to a remote storage bucket for you::

  with lola.run(
      remote_location="gs://somewhere",
      remote_credentials="service_account.json",
  ) as run:
      # train and log ...

  # All artifacts are uploaded now


The remote location can also be configured with the `.lola.toml` file.

Additionally, Lola offers some helpers to analyse the your experiments:
