Tensorflow.js tf.loadGraphModel() Function
Tensorflow.js is an open-source library developed by Google for running machine learning models as well as deep learning neural networks in the browser or node environment.
The .loadGraphModel() function is used to Load a graph model given a URL to the model definition.
tf.loadGraphModel (modelUrl, options)
- modelUrl: The first tensor input that can be of type string or io.IOHandler. This parameter is the URL or an io.IOHandler that helps to load the models.
- options: The second tensor input that is optional. Options are for the HTTP request, which allows sending credentials and custom headers. The types of options are –
- requestInit: RequestInit are for HTTP requests.
- onProgress: OnProgress is for progress callback.
- fetchFunc: It is a function used to override the window.fetch function.
- strict: Strict is a loading model: whether it is an extraneous weight or missing weights should trigger an Error.
- weightPathPrefix: Path prefix is for weight files which is by default that is calculated from the path of the model JSON file.
- fromTFHub: It is a boolean which is whether the module or model is to be loaded from TF Hub.
Return value: It returns the Promise <tf.GraphModel>.
Example 1: In this example, we are loading MobileNetV2 from a URL and making a prediction with a zeros input.
Tensor [[-0.1412081, -0.5656458, 0.7578365, ..., -1.0148169, -0.81284, 1.1898142],]
Example 2: In this example, we are loading MobileNetV2 from a TF Hub URL and making a prediction with a zeros input.
Tensor [[-1.0764486, 0.0097444, 1.1630495, ..., -0.345558, 0.035432, 0.9112286],]
