Querying Training Job Logs

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 and version_id.

      
           from modelarts.session import Session
from modelarts.estimator import Estimator
session = Session()
estimator = Estimator(modelarts_session=session, job_id="182626", version_id="278813")
job_log = estimator.get_job_log(log_file='job-job-0713-191758.0')
print(job_log)

Method 2: Use the training job created in Creating a Training Job.

      
           job_log = job_instance.get_job_log(log_file='job-job-0713-191758.0')
print(job_log)

Method 3: Use the training job version object returned in Querying the List of Training Job Versions.

      
           job_log = job_version_instance_list[0].get_job_log(log_file='job-job-0713-191758.0')
print(job_log)
