You can set the number of attempts to\nrerun the task on failure and the delay between subsequent retries.\n\nUse the following code sample to configure the failure policy of a pipeline task\nnamed `train_op` by using the\n[`set_retry`](https://kubeflow-pipelines.readthedocs.io/page/source/dsl.html#kfp.dsl.PipelineTask.set_retry)\nmethod in the Kubeflow Pipelines SDK: \n\n from kfp import dsl\n\n @dsl.pipeline(name='custom-container-pipeline')\n def pipeline():\n generate = generate_op()\n train = (\n train_op(\n training_data=generate.outputs['training_data'],\n test_data=generate.outputs['test_data'],\n config_file=generate.outputs['config_file'])\n .set_retry(\n num_retries=\u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-n\"\u003eNUMBER_OF_RETRIES\u003c/span\u003e\u003c/var\u003e,\n backoff_duration='\u003cvar translate=\"no\"\u003eBACKOFF_DURATION\u003c/var\u003e',\n backoff_factor=\u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-n\"\u003eBACKOFF_FACTOR\u003c/span\u003e\u003c/var\u003e,\n backoff_maxk_duration='\u003cvar translate=\"no\"\u003eBACKOFF_MAX_DURATION\u003c/var\u003e'\n )\n\nReplace the following:\n\n- \u003cvar translate=\"no\"\u003eNUMBER_OF_RETRIES\u003c/var\u003e: The number of times to retry the task upon failure.\n\n- \u003cvar translate=\"no\"\u003eBACKOFF_DURATION\u003c/var\u003e: Optional.

These values must be available when you compile the pipeline."]]
