Sample Code

In ModelArts notebook, you do not need to enter authentication parameters for session authentication. For details about session authentication of other development environments, see Session Authentication.

Scenario 1: Obtain all model objects of a user.

from modelarts.session import Session
from modelarts.model import Model

session = Session()
model_object_list = Model.get_model_object_list(session)

Scenario 2: Obtain a model object based on the search criteria.

from modelarts.session import Session
from modelarts.model import Model

session = Session()
model_object_list = Model.get_model_object_list(session, model_status="published", model_name="digit", order="desc")

Parameters

After you obtain a model list, the size of the list is equal to the number of models that have been deployed by the current user. Each element in the list is a model object. The object attributes are the same as those in Querying the Details About a Model. For example, in model_list = [model_instance1, model_instance2, model_instance3 ...], each model_instance in the list is a model API that can be called.
The model list can be obtained based on the query parameters. Table 1 describes the query parameters.
When you obtain a model list, details about the models are returned. See Table 2 and Table 3.
A maximum of 150 model objects can be obtained.

**Table 1** Query parameters
