 # Conditional Density Estimation (CDE)
 
-**Update:** Conditional Density Estimation now runs with PyTorch on the `main` branch (formerly `pytorch-migration`); the legacy TensorFlow implementation lives in the `tensorflow` branch. All core estimators, runners, and examples are tested with the latest PyTorch release.
