DeepCAVE

DeepCAVE is a visualization and analysis tool for AutoML (especially for the sub-problem hyperparameter optimization) runs. The framework is programmed on top of Dash and therefore entirely interactive. Multiple and diverse plugins make it possible to efficiently generate insights and bring the human back in the loop. Moreover, the powerful run interface and the modularized plugin structure allow extending the tool at any time effortlessly.

Following features are provided:

• Interactive Dashboard (completely written in Python) to self-analyze optimization runs/processes.
• Analyzing while optimizing (run changes are automatically detected).
• A large collection of plugins to explore multiple areas like performance, hyperparameter and budget analysis.
• Save your runs using DeepCAVE's native recorder.
• Support for many optimizers using converter (e.g., DeepCAVE, SMAC and BOHB).
• Select runs directly from a working directory in the interface.
• Select groups of runs for combined analysis.
• Modularized plugin structure with access to selected runs/groups to provide maximal flexibility.
• Asynchronous execution of expensive plugins and caching of their results.
• Help buttons and integrated documentation in the interface helps you to understand the plugins.
• Use the matplotlib mode to customize and save the plots for your publication.
• The API mode gives you full access to the code, while you do not have to interact with the interface. Otherwise, you can also make use of the raw data, provided by every plugin.

Installation

First, make sure you have redis-server installed on your computer.

Afterwards, follow the instructions to install DeepCAVE:

conda create -n DeepCAVE python=3.9
conda activate DeepCAVE
conda install -c anaconda swig
pip install DeepCAVE

If you want to contribute to DeepCAVE use the following steps instead:

git clone https://github.com/automl/DeepCAVE.git
conda create -n DeepCAVE python=3.9
conda activate DeepCAVE
conda install -c anaconda swig
make install-dev

Please visit the documentation to get further help (e.g. if you can not install redis server or you are on a mac).

Recording

A minimal example is given to show the simplicity yet powerful API to record runs. However, existing optimizers like BOHB, SMAC, Auto-Sklearn, Auto-PyTorch are supported natively.

import ConfigSpace as CS
from deepcave import Recorder, Objective


configspace = CS.ConfigurationSpace(seed=0)
alpha = CS.hyperparameters.UniformFloatHyperparameter(
    name='alpha', lower=0, upper=1)
configspace.add_hyperparameter(alpha)

accuracy = Objective("accuracy", lower=0, upper=1, optimize="upper")
mse = Objective("mse", lower=0)

with Recorder(configspace, objectives=[accuracy, mse]) as r:
    for config in configspace.sample_configuration(100):
        for budget in [20, 40, 60]:
            r.start(config, budget)
            # Your code goes here
            r.end(costs=[0.5, 0.5])

Visualizing and Evaluating

The webserver as well as the queue/workers can be started by simply running:

deepcave --open

If you specify --open your webbrowser automatically opens at http://127.0.0.1:8050/. You can find more arguments and information (like using custom configurations) in the documentation.
