MobileModelModule.MobileModel

Methods​

download​

▸ download(modelPath): Promise<string>

Download a model to the local file system and return the local file path as a model. If the model path is a file path already, it will return the same path as a result.

Parameters​

NameTypeDescription
modelPathModelPathThe model path as require or uri (i.e., require).

Returns​

Promise<string>

execute​

▸ execute<T>(modelPath, params): Promise<ModelResult<T>>

Run inference on a model.

const classificationModel = require('../models/mobilenet_v3_small.ptl');

// or

const classificationModel = require('https://example.com/models/mobilenet_v3_small.ptl');

const image: Image = await ImageUtils.fromURL('https://image.url');

const { result: {maxIdx} } = await MobileModel.execute(
  classificationModel,
  {
    image,
  }
);

const topClass = ImageClasses(scores);

Type parameters​

Name
T

Parameters​

NameTypeDescription
modelPathModelPathThe model path as require or uri (i.e., require).
paramsanyThe input parameters for the model.

Returns​

Promise<ModelResult<T>>

preload​

▸ preload(modelPath): Promise<void>

Preload a model. If a model is not preloaded, it will be loaded during the first inference call. However, the first inference time will therefore take significantly longer. This function allows to preload a model ahead of time before running the first inference.

Parameters​

NameTypeDescription
modelPathModelPathThe model path as require or uri (i.e., require).

Returns​

Promise<void>

unload​

▸ unload(): Promise<void>

Unload all model. If any model were loaded previously, they will be discarded. This function allows to load a new version of a model without restarting the app.

Returns​

Promise<void>
