Response 200

A successful response provides an array of training status details for a LUIS app. Each element in the response array provides training status for a model (intent or entity).

Note: Training status is not provided for prebuilt entities because they are pretrained.

The modelId property corresponds to an intent or entity. To get the name and type of each model, use the models API which has a request URL in this format:

  • https://westus.api.cognitive.microsoft.com/luis/api/v2.0/apps//versions//models

The details property for each model can contain the following fields:

  • statusId :An integer from 0 to 3 that corresponds to the value of the status field.

  • status: A string with one of the following values:

    • Success

    • UpToDate

    • InProgress

    • Fail

      • If the status is 'Fail', the failureReason property provides the reason for failure.
  • exampleCount: The number of examples used for training. In the case of the None intent or prebuilt domain intents and entities, this number includes examples provided internally by the system as well as examples you added to your LUIS app.

  • failureReason: A string that indicates the reason training failed. The value 'FewLabels' means that no labeled examples were provided for training.

  • trainingDateTime: A string indicating the time the model was last trained. The value uses the ISO 8601 format for representing times in UTC (Coordinated Universal Time) with a UTC designator ('Z'), for example: '2017-08-10T01:08:34Z

Response 400

This response can occur for any of the following reasons:

  • You need to submit a training request before you request training status.
  • The format of appId is incorrect.
  • The value of appId is incorrect.
  • The value of versionId is incorrect.

If you need to submit a training request before you request training status:

{
  "error": {
    "code": "BadArgument",
    "message": "Training request is required before getting training status"
  }
}

If the format of appId is incorrect:
{
  "error": {
    "code": "BadArgument",
    "message": "Value cannot be null. Parameter name: source"
  }
}

If the value of appId is incorrect:
{
  "error": {
    "code": "BadArgument",
    "message": "Cannot find an application with the specified ID"
  }
}

If versionId is incorrect:

{
  "error": {
    "code": "BadArgument",
    "message": "Cannot find a task with the specified version ID"
  }
}

Response 401

You do not have access.

Reasons can include:

  • used endpoint subscription key, instead of authoring key
  • invalid, malformed, or empty authoring key
  • authoring key doesn't match region
  • you are not the owner or collaborator
  • invalid order of API calls

{
  "statusCode": 401,
  "message": "Access denied due to invalid subscription key. Make sure to provide a valid key for an active subscription."
}
