+=======================================
 
-`PyTorchLightning <https://lightning.ai/docs/pytorch/stable/>`_ as backhand is done to offer
-professional AI researchers and machine learning engineers the possibility of using advancement
-training strategies provided by the library, such as multiple device training, modern model compression techniques,
-gradient accumulation, and so on. In addition, it provides the possibility to add arbitrary
-self-contained routines (callbacks) to the training for easy extensions without the need to touch the
-underlying code.

-The high-level structure of the package is depicted in our API. The pipeline to solve differential equations
-with PINA follows just five steps: problem definition, model selection, data generation, solver selection, and training.

-`PINN <https://www.sciencedirect.com/science/article/abs/pii/S0021999118307125>`_ is a novel approach that
-involves neural networks to solve differential equations in an unsupervised manner, while respecting
-any given law of physics described by general differential equations. Proposed in "*Physics-informed neural
-networks: A deep learning framework for solving forward and inverse problems
-involving nonlinear partial differential equations*", such framework aims to

-neural network is able to generalize across different instances of the differential equations (e.g. different forcing
