Model Metadata

A full model is composed of 3 types of entities:

  1. The model
  2. The instances (also called variations)
  3. The instance versions (also called version of a variation)

Let's take the example of efficientnet to explain these entities.

A model like efficientnet contains multiple instances.

An instance is a specific variation of the model (e.g. B0, B1, ...) with a certain framework (e.g. TensorFlow2).

You can find more documentation on how to name your model and variations here.

Model

To create a model, a special model-metadata.json file must be specified.

Here's a basic example for model-metadata.json:

{
  "ownerSlug": "INSERT_OWNER_SLUG_HERE",
  "title": "INSERT_TITLE_HERE",
  "slug": "INSERT_SLUG_HERE",
  "subtitle": "",
  "isPrivate": true,
  "description": "Model Card Markdown, see below",
  "publishTime": "",
  "provenanceSources": ""
}

You can also use the API command kaggle models init -p /path/to/model to have the API create this file for you for a new model. If you wish to get the metadata for an existing model, you can use kaggle models get username/model-slug.

Contents

We currently support the following metadata fields for models.

  • ownerSlug: the slug of the user or organization
  • title: the model's title
  • slug: the model's slug (unique per owner)
  • subtitle: the model's subtitle
  • isPrivate: whether or not the model should be private (only visible by the owners). If not specified, will be true
  • description: the model's card in markdown syntax (see the template below)
  • publishTime: the original publishing time of the model
  • provenanceSources: the provenance of the model

Description

You can find a template of the model card on this wiki page: https://github.com/Kaggle/kaggle-api/wiki/Model-Card

Model Instance (a.k.a Model Variation)

To create a model instance, a special model-instance-metadata.json file must be specified.

Here's a basic example for model-instance-metadata.json:

{
  "ownerSlug": "INSERT_OWNER_SLUG_HERE",
  "modelSlug": "INSERT_EXISTING_MODEL_SLUG_HERE",
  "instanceSlug": "INSERT_INSTANCE_SLUG_HERE",
  "framework": "INSERT_FRAMEWORK_HERE",
  "overview": "",
  "usage": "Usage Markdown, see below",
  "licenseName": "Apache 2.0",
  "fineTunable": False,
  "trainingData": []
}

You can also use the API command kaggle models instances init -p /path/to/model-instance to have the API create this file for you for a new model instance.

Contents

We currently support the following metadata fields for model instances.

  • ownerSlug: the slug of the user or organization of the model
  • modelSlug: the existing model's slug
  • instanceSlug: the slug of the instance
  • framework: the instance's framework (see the list below)
  • overview: a short overview of the instance
  • usage: the instance's usage in markdown syntax (see more info below)
  • licenseName: the name of the license (see the list below)
  • fineTunable: whether the instance is fine tunable
  • trainingData: a list of training data in the form of strings, URLs, Kaggle Datasets, etc...

Usage

Snippets of code on how to use the model in markdown.

The following template variables can be used in this markdown:

  • ${VERSION_NUMBER} is replaced by the version number when rendered
  • ${VARIATION_SLUG} is replaced by the variation slug when rendered
  • ${FRAMEWORK} is replaced by the framework name
  • ${PATH} is replaced by /kaggle/input/<model_slug>/<framework>/<variation_slug>/<version>.
  • ${FILEPATH} is replaced by /kaggle/input/<model_slug>/<framework>/<variation_slug>/<version>/<filename>. This value is only defined if the databundle contain a single file
  • ${URL} is replaced by the absolute URL of the model
