+# PyTorch Glow: Generative Flow with Invertible 1x1 Convolutions
+
+![MIT License](https://img.shields.io/badge/License-MIT-blue.svg)
+[![Paper](https://img.shields.io/badge/ArXiv-Paper-red)](https://arxiv.org/abs/1807.03039)
+
+Glow is a normalizing flow model introduced by OpenAI that uses an invertible generative architecture.
+Glow’s flow blocks consist of 3 components: act norm, 1x1 invertible convolutions and affine coupling layers.
+<br></br>
+This repository contains the complete workflow for training and testing Glow. All code was developed during the GenAI UCU course.
+Here are presented:
+- model implementation from scratch
+- train script with hydra configs
+- tensorboard logging
+- DDP trainer
+- tests with pytest
+- CI using github actions
