filters - the search filters to match against the loaded model

device - the device the loaded model should use

progress - the progress tracker to update while loading the model

Returns:

the loaded model

Throws:

java.io.IOException - for various exceptions loading data from the repository

ai.djl.repository.zoo.ModelNotFoundException - if no model with the specified criteria is found

ai.djl.MalformedModelException - if the model data is malformed
