wrap lenstronomy for efficient simulation generation

Project description

Welcome to deeplenstronomy!

status status status status

deeplenstronomy is a tool for simulating large datasets for applying deep learning to strong gravitational lensing. It works by wrapping the functionalities of lenstronomy in a convenient yaml-style interface, allowing users to embrace the astronomer part of their brain rather than their programmer part when generating training datasets.

Installation

With conda (Recommended)

  • Step 0: Set up an environment. This can be done straightforwardly with a conda installation:
conda create -n deeplens python=3.7 jupyter scipy pandas numpy matplotlib astropy h5py PyYAML mpmath future
conda activate deeplens
  • Step 1: pip install lenstronomy
  • Step 2: pip install deeplenstronomy

With pip

  • Step 1: pip install deeplenstronomy

Getting Started and Example Notebooks

Start by reading the Getting Started Guide to familiarize yourself with the deeplenstronomy style.

After that, check out the example notebooks below:

API Documentation

deeplenstronomy is designed so that users only need to work with their personal configuration files and the dataset generatation and image visualization functions. However, if you would like to view the full API documentation, you can visit the docs page.
