# Welcome to `deeplenstronomy`!

`deeplenstronomy` is a tool for simulating large datasets for applying deep learning to strong gravitational lensing.
It works by wrapping the functionalities of [`lenstronomy`](https://github.com/sibirrer/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](https://deepskies.github.io/deeplenstronomy/Notebooks/)
Start by reading the [Getting Started Guide](https://deepskies.github.io/deeplenstronomy/Notebooks/GettingStarted.html) to familiarize yourself with the `deeplenstronomy` style.

## 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](https://deepskies.github.io/deeplenstronomy/docs/) page.
