Function

This API is used to replace a specified PyTorchJob. The following fields can be replaced:

metadata.labels
metadata.annotations
spec.activeDeadlineSeconds
spec.ttlSecondsAfterFinished
spec.cleanPodPolicy

URI

PUT /apis/kubeflow.org/v1/namespaces/{namespace}/pytorchjobs/{name}

**Table 1** Path parameters
Parameter	Mandatory	Description
name	Yes	Name of the PyTorchJob.
namespace	Yes	Object name and auth scope, such as for teams and projects.

**Table 2** Query parameter
Parameter	Mandatory	Description
pretty	No	If 'true', then the output is pretty printed.
