Build from Source¶
Install nightly from the source. Note that it contains all the bug fixes and newly released features that are not published yet. This is the bleeding edge, so use it at your own discretion.
pip install https://github.com/Lightning-AI/lightning/archive/refs/heads/master.zip -U
Install future patch releases from the source. Note that the patch release contains only the bug fixes for the recent major release.
pip install https://github.com/Lightning-AI/lightning/archive/refs/heads/release/stable.zip -U
Optimized for model development¶
If you are deploying models built with Lightning in production and require few dependencies, try using the optimized lightning[pytorch] package:
pip install lightning
Custom PyTorch Version¶
To use any PyTorch version visit the PyTorch Installation Page.
Optimized for ML workflows (lightning Apps)¶
If you are deploying workflows built with Lightning in production and require fewer dependencies, try using the optimized lightning[apps] package:
