View series of images#

If you have logged images as a series with the append() or extend() (previously log()) method, you can browse and navigate the images in the gallery view. The corresponding epoch, index, or timestamp is displayed for each image in the series.

This can help you analyze your image data and results:

  • To perform a sanity check or gain a better understanding of your data, you can navigate through the image samples quickly, or browse your samples with a specific index.
  • By logging a series of images once or every few epochs, you can visualize the progression of an image or batch of images throughout the training process, to understand how model predictions have changed over time.
  • To assess the model and direction of the training, you can view the progression of the confusion matrix or gradients over the training process.
  • For high-accuracy segmentation tasks, you can zoom in on small parts of each image.
  1. In Run details, navigate to Images or create a custom dashboard with an image widget.
  2. Locate the image series field you want to display.

You can use the index slider to visualize the progression of an image or batch throughout the training process.

In carousel mode, you can use the play button () to automate the animation.

Pinning an image#

Pinning allows you to select particular images from the series, for example, to compare two specific images between epochs or cells.

To pin an image to the top of the gallery, hover over it and click the pin icon ().

Zooming an image#

To enter zoom mode, hover over an image and click the magnifying glass ().

To zoom in or out, you can use:

  • Mouse wheel while holding Ctrl
