Obtaining the Details About a Training Job

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.

Method 1: Use the specified job_id.

from modelarts.session import Session
from modelarts.estimatorV2 import Estimator
session = Session()
estimator = Estimator(session=session, job_id="618222c4-dc2f-4cfe-bc49-72b075b7552f")
job_info = estimator.get_job_info()
print(job_info)

Method 2: Use the training job created in Creating a Training Job.
```
job_info = job_instance.get_job_info()
print(job_info)
```
