In the REST API docs for the Version resource you can see in the description for the framework field that:
Valid values are TENSORFLOW, SCIKIT_LEARN, and XGBOOST
enum(Framework) is just the field's type. Also, from that same link: isDefault field is output only. You shouldn't include it in the request to create a model version. From the docs for the create method:
If you want a new version to be the default, you must call
projects.models.versions.setDefault.
So, to create a new model version and set it as default via REST API:
Put the request payload in a json file:
{
"name": "v4",
"description": "This is test Version created by API",
"deploymentUri": "gs://car-hertz/vans-uk-hertz/output/v1/F0/export/exporter/1531390162/",
"runtimeVersion": "1.4",
"framework": "TENSORFLOW",
"pythonVersion": "2.7"
}
Create the version by running in a shell the following (I like to use a gcurl alias):
alias gcurl='curl -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" -H "Content-Type: application/json" '
gcurl -X POST -T "$REQUEST_FILEPATH" https://ml.googleapis.com/v1/projects/$PROJECT/models/$MODEL/versions
Set the above as the default:
gcurl -X POST https://ml.googleapis.com/v1/projects/$PROJECT/models/$MODEL/versions/v4:setDefault
