|
|
Lightning is a way to organize your PyTorch code to decouple the science code from the engineering.
|
|
It's more of a style-guide than a framework.
|
|
|
|
In Lightning, you organize your code into 3 distinct categories:
|
|
|
|
1. Research code (goes in the LightningModule).
|
|
2. Engineering code (you delete, and is handled by the Trainer).
|
|
3. Non-essential research code (logging, etc. this goes in Callbacks).
|
|
|
|
Although your research/production project might start simple, once you add things like GPU AND TPU training,
|
|
16-bit precision, etc, you end up spending more time engineering than researching.
|
|
Lightning automates AND rigorously tests those parts for you.
|
|
|
|
Overall, Lightning guarantees rigorously tested, correct, modern best practices for the automated parts.
