身份验证

The Authentication properties of this activity allow you to execute it via on-premises robots. Before configuring these properties, ensure you have fulfilled the prerequisites mentioned in the Configuring Authentication page. Once these steps are completed, you can then proceed to fill in the Authentication properties of the activity.

  • Runtime Credentials Asset - Use this field when you need to access Document Understanding generative classification features while the robot is connected to a local Orchestrator, or from a different tenant. You can choose to enter a Credential Asset, for authentication purposes, in one of the following ways:
    • From the dropdown list, select the desired Credential Asset from the Orchestrator to which the UiPath® Robot is connected to.

    • 手动输入 Orchestrator 凭据资产的路径,您将在其中存储用于访问生成式功能的外部应用程序凭据。

      路径的格式应为: <OrchestratorFolderName>/<AssetName>

  • Runtime Tenant Url - Use this field, alongside the Runtime Credentials Asset field. Enter the URL of the tenant that the robot will connect to in order to execute the generative classification. The URL should be in the following format: https://<baseURL>/<OrganizationName>/<TenantName>.

常见

  • “显示名称”- 活动的显示名称。

其他

  • “私有”- 选中后将不再以“Verbose”级别记录变量和参数的值。

服务器

  • RetryOnFailure - Automatically retries the machine learning model execution, to eliminate transient network errors. If checked, the activity retries the execution.
  • Timeout (milliseconds) - Specifies the amount of time (in milliseconds) to wait for a response from the server before an error is thrown. The default value is 100000 milliseconds (100 seconds).

使用“管理提示”向导

The Generative Classifier Prompt wizard allows you to define the prompt for document types. The prompt is used to identify Document Types, provided as key-value pairs, where the key represents the name of the Document Type and the value a description for it, helping the classifier identify such documents.

用于输入键值对的生成式分类器提示词

  1. Select a Document Type from the list of document types defined in the Configure Classifier wizard.
  2. In Document Type details, add an optional value to define additional details about the document type. This can be a short description of the document type. The maximum number of characters allowed is 1000.
