Hubble's Law

A Cosmic Data Story about Hubble's Law

Requirements

• Python-based Cosmic Data Stories now run on solara.
• hubbleds requires the base cosmicds to be installed.
• Developers need an API key to access the CosmicDS database. Contact the team for more information.

Installation

• Optional but recommended, set up a new python environment.
• Install pip if you don't already have it.
• If you haven't already installed these packages,

  $ pip install solara
  $ pip install python-dotenv

• Pull down both the cosmicds & hubbleds repos.
• Inside the cosmicds folder in your terminal, $ pip install -e .
• Inside the hubbleds folder in your terminal, $ pip install -e .

Running HubbleDS

Inside the hubbleds folder in your terminal,

    $ CDS_API_KEY="<your api key>" solara run hubbleds.pages --theme-variant dark

Development Tip

If you update .css, you have to force refresh your browser (shift-command-r on a mac) for the changes to register.

Legacy Code

As of 4/30/2024, the voila-based code has been moved to the legacy branch.

To run the legacy code, you also need the legacy branch of the cosmicds repo.

• Pull down both those branches and set up a new python environment.
• In the cosmicds directory: $ pip install -e .
• In the hubbleds directory: $ pip install -e .
• You may need to pip install any missing dependencies.
• If you have trouble installing voila, you may need to downgrade your version of node.js to a Long Term Support (LTS) version (14.x or 16.x).
• Open jupyter notebook and run src/hubbleds/HubbleDS.ipynb

or

• From the command line: $ cosmicds hubble
