Strong lensing package using jax
Project description
paltax is a package for conducting simulation-based inference on strong gravitational lensing images.
Installation
paltax is installable via pip:
$ pip install paltax
For the most up-to-date version of paltax install directly from the git repository.
$ git clone https://github.com/swagnercarena/paltax.git
$ cd path/to/paltax/
$ pip install -e .
Usage
The main functionality of paltax is to train (sequential) neural posterior estimators with on-the-fly data generation. To train a model with paltax you need a training configuration file that is passed to main.py:
$ python main.py --workdir=path/to/model/output/folder --config=path/to/training/configuration
paltax comes preloaded with a number of training configuration files which are described in paltax/TrainConfigs/README.rst. These training configuration files require input configuration files, examples of which can be found in paltax/InputConfigs/.
Demos
paltax comes with a tutorial notebook for users interested in using the package.
Figures
Code for generating the plots included in some of the publications using paltax can be found under the corresponding arxiv number in the paltax/notebooks/papers/ folder.
