-Define the metrics that you want to send to CloudWatch by specifying a list of metric names and regular expressions as the `metric_definitions` argument when you initialize an `Estimator` object. For example, if you want to monitor both the `train:error` and `validation:error` metrics in CloudWatch, your `Estimator` initialization would look like the following example:
-    
-    
-    import sagemaker
-    from sagemaker.estimator import Estimator
-    
-    estimator = Estimator(
-        image_uri="your-own-image-uri",
-        role=sagemaker.get_execution_role(), 
-        sagemaker_session=sagemaker.Session(),
-        instance_count=1,
-        instance_type='ml.c4.xlarge',
-        metric_definitions=[
-           {'Name': 'train:error', 'Regex': 'Train_error=(.*?);'},
-           {'Name': 'validation:error', 'Regex': 'Valid_error=(.*?);'}
-        ]
-    )
