``paltax`` is a package for conducting simulation-based inference on strong gravitational lensing images.

Installation
------------

``paltax`` is installable via pip:

.. code-block:: bash

    $ pip install paltax

For the most up-to-date version of paltax install directly from the git repository.

.. code-block:: bash

    $ 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:

.. code-block:: bash

    $ 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.
