      • hasHyperParameters

        public final boolean hasHyperParameters()
        For responses, this returns true if the service returned a value for the HyperParameters property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • hyperParameters

        public final Map<String,​String> hyperParameters()

        Algorithm-specific parameters.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasHyperParameters() method.

        The value of the ProfilerConfig property for this object.
      • hasProfilerRuleConfigurations

        public final boolean hasProfilerRuleConfigurations()
        For responses, this returns true if the service returned a value for the ProfilerRuleConfigurations property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • profilerRuleConfigurations

        public final List<ProfilerRuleConfiguration> profilerRuleConfigurations()

        Configuration information for Amazon SageMaker Debugger rules for profiling system and framework metrics.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasProfilerRuleConfigurations() method.

        Returns:
        Configuration information for Amazon SageMaker Debugger rules for profiling system and framework metrics.
      • hasProfilerRuleEvaluationStatuses

        public final boolean hasProfilerRuleEvaluationStatuses()
        For responses, this returns true if the service returned a value for the ProfilerRuleEvaluationStatuses property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • profilerRuleEvaluationStatuses

        public final List<ProfilerRuleEvaluationStatus> profilerRuleEvaluationStatuses()

        Evaluation status of Amazon SageMaker Debugger rules for profiling on a training job.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasProfilerRuleEvaluationStatuses() method.

        Returns:
        Evaluation status of Amazon SageMaker Debugger rules for profiling on a training job.
      • hasEnvironment

        public final boolean hasEnvironment()
        For responses, this returns true if the service returned a value for the Environment property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • environment

        public final Map<String,​String> environment()

        The environment variables to set in the Docker container.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasEnvironment() method.

        Returns:
        The environment variables to set in the Docker container.
      • retryStrategy

        public final RetryStrategy retryStrategy()

        The number of times to retry the job when the job fails due to an InternalServerError.

        Returns:
        The number of times to retry the job when the job fails due to an InternalServerError.
      • infraCheckConfig

        public final InfraCheckConfig infraCheckConfig()

        Contains information about the infrastructure health check configuration for the training job.

        Returns:
        Contains information about the infrastructure health check configuration for the training job.
      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
