publish_model {AzureVision}R Documentation

Publish, export and unpublish a Custom Vision model iteration

Description

Publish, export and unpublish a Custom Vision model iteration

Usage

publish_model(model, name, prediction_resource)

unpublish_model(model, confirm = TRUE)

export_model(model, format, destfile = basename(httr::parse_url(dl_link)$path))

list_model_exports(model)

Arguments

model

A Custom Vision model iteration object.

name

For publish_model, the name to assign to the published model on the prediction endpoint.

prediction_resource

For publish_model, the Custom Vision prediction resource to publish to. This can either be a string containing the Azure resource ID, or an AzureRMR resource object.

confirm

For unpublish_model, whether to ask for confirmation first.

format

For export_model, the format to export to. See below for supported formats.

destfile

For export_model, the destination file for downloading. Set this to NULL to skip downloading.

Details

Publishing a model makes it available to clients as a predictive service. Exporting a model serialises it to a file of the given format in Azure storage, which can then be downloaded. Each iteration of the model can be published or exported separately.

The format argument to export_model can be one of the following. Note that exporting a model requires that the project was created with support for it.

Value

export_model returns the URL of the exported file, invisibly if it was downloaded.

list_model_exports returns a data frame detailing the formats the current model has been exported to, along with their download URLs.
