Create or update metadata about an artifact.


usage: gto annotate [-r <text>] [--type <text>] [--path <text>]
                    [-e] [--label <text>] [-d <text>] [--commit]
                    [--push] [-h]

  name             Artifact name


The command adds the artifact annotation to artifacts.yaml file. Feel free to modify the file directly!

For example,

$ gto annotate awesome-model \
  --type model \
  --path models/neural_network.h5 \
  --label ml
  --label cool
  --description "This model is very cool"

will create

  description: This model is very cool
    - ml
    - cool
  path: models/neural_network.h5
  type: model

This information can be later retrieved by running gto describe command.

Don't forget to commit artifacts.yaml with Git to associate it with the latest artifact version and stage in any copy of the repo.

By default GTO saves artifact as virtual. Use the --must_exist flag to tell GTO the artifact file is committed to Git.

  • Physical files/directories are committed to the repo. When you create a new version or assign a stage to it, Git guarantees that it's immutable — you can return a year later and get the same artifact by providing a version.

  • Virtual artifacts could be an external path (e.g. s3://mybucket/myfile) or a local path to a metafile representing an externally stored artifact file (as with DVC). In this case, GTO can't pin versions to a physical state of the artifact and guarantee its immutability later, e.g. if s3://mybucket/myfile changes the registry won't know it, nor have a way to recover the original file.


  • -r <text>, --repo <text> - Local or remote repository [default: .]
  • --type <text> - Artifact type
  • --path <text> - Artifact path
  • -e, --must-exist - Verify artifact is committed to Git
  • --label <text> - Labels to add to artifact
  • -d <text>, --description <text> - Artifact description
  • --commit - Automatically commit changes due to this command (experimental)
  • --push - Push created commit automatically (experimental) - will set commit=True
  • -h, --help - Show this message and exit.
