Querying Algorithm Details

Function

This API is used to obtain the details of a specified algorithm on ModelArts.

This API applies to the following scenario: When you need to view the detailed configuration and attributes of a specific algorithm, you can use this API to obtain the algorithm details. Before using this API, ensure that you have obtained the algorithm ID and have the permission to view algorithm details. After the query is complete, the platform returns the details, including the algorithm name, description, and version. If the algorithm ID does not exist or you do not have the operation permission, the API will return an error message.

Debugging

You can debug this API through automatic authentication in API Explorer or use the SDK sample code generated by API Explorer.

Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.

If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.
If you are using identity policy-based authorization, the following identity policy-based permissions are required.
