# AWS::SageMaker::HyperParameterTuningJob ResourceLimits
<a name="aws-properties-sagemaker-hyperparametertuningjob-resourcelimits"></a>

Specifies the maximum number of training jobs and parallel training jobs that a hyperparameter tuning job can launch.

## Syntax
<a name="aws-properties-sagemaker-hyperparametertuningjob-resourcelimits-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-sagemaker-hyperparametertuningjob-resourcelimits-syntax.json"></a>

```
{
  "[MaxNumberOfTrainingJobs](#cfn-sagemaker-hyperparametertuningjob-resourcelimits-maxnumberoftrainingjobs)" : {{Integer}},
  "[MaxParallelTrainingJobs](#cfn-sagemaker-hyperparametertuningjob-resourcelimits-maxparalleltrainingjobs)" : {{Integer}},
  "[MaxRuntimeInSeconds](#cfn-sagemaker-hyperparametertuningjob-resourcelimits-maxruntimeinseconds)" : {{Integer}}
}
```

### YAML
<a name="aws-properties-sagemaker-hyperparametertuningjob-resourcelimits-syntax.yaml"></a>

```
