# visualizers

Python API: `luxonis_train.attached_modules.visualizers`

Visualizers that draw the predictions of a node.

A visualizer returns one batch of images, or a pair of batches.
[combine_visualizations](https://docs.luxonis.com/software-v3/ai-inference/model-source/training/luxonis-train/luxonis-train-api-reference/attached_modules/visualizers/utils.md)
puts a pair side by side, with the first batch on the left, before the trainer logs it. In a pair, the first batch shows the
labels and the second the predictions.
[ClassificationVisualizer](https://docs.luxonis.com/software-v3/ai-inference/model-source/training/luxonis-train/luxonis-train-api-reference/attached_modules/visualizers/classification_visualizer.md)
returns the text images and the probability plots instead, and
[EmbeddingsVisualizer](https://docs.luxonis.com/software-v3/ai-inference/model-source/training/luxonis-train/luxonis-train-api-reference/attached_modules/visualizers/embeddings_visualizer.md)
returns a KDE plot and a scatter plot.

Attach a visualizer in the `visualizers` field of a node. `trainer.n_log_images` caps how many images each node logs on a
validation or test epoch.
