Obtaining Training 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.

from modelarts.session import Session
from modelarts.estimatorV2 import Estimator
session = Session()
estimator = Estimator(session=session, job_id="your job id")
info = estimator.get_job_log()
print(info)

Method 2: Use the training job created in Creating a Training Job.
```
log = job_instance.get_job_log(task_id="worker-0")
print(log)
```

Parameters

**Table 1** Parameters for initializing the Estimator
Parameter	Mandatory	Type	Description
session	Yes	Object	Session object. For details about the initialization method, see Session Authentication.
job_id	Yes	String	ID of a training job. You can obtain job_id using the training job created in Creating a Training Job, for example, job_instance.job_id, or from the response obtained in Obtaining Training Jobs.

**Table 2** **get_job_log** request parameters
Parameter	Mandatory	Type	Description
task_id	No	String	ID of a worker node for obtaining logs. It defaults to worker-0. If train_instance_count is set to 2 when you create a training job, the value of this parameter can be worker-0 or worker-1.

**Table 3** Response parameters
Parameter	Type	Description
content	String	Log content If the size of the log file does not exceed the limit allowed (n MB), all logs are returned. If the size of the log file exceeds the limit allowed (n MB), the latest n MB logs are returned.
current_size	Integer	Size of the returned log file, in bytes. The maximum value is 5 MB.
full_size	Integer	Size of a complete log file, in bytes.

**Table 4** Response for the failure to call a training API
Parameter	Type	Description
error_msg	String	Error message when calling an API failed. This parameter is unavailable if an API is successfully called.
error_code	String	Error code when calling an API failed. For details, see Error Codes. This parameter is unavailable if an API is successfully called.
error_solution	String	Solution to an API calling failure. This parameter is unavailable if an API is successfully called.
