ImageClassifier

Instance Constructors

new ImageClassifier(modelPathPrefix: String, inputDescriptors: IndexedSeq[DataDesc], contexts: Array[Context] = Context.cpu(), epoch: Option[Int] = Some(0))

modelPathPrefix
Path prefix from where to load the model artifacts. These include the symbol, parameters, and synset.txt. Example: file://model-dir/resnet-152 (containing resnet-152-symbol.json, resnet-152-0000.params, and synset.txt).
inputDescriptors
Descriptors defining the input node names, shape, layout and type parameters
contexts
Device contexts on which you want to run inference; defaults to CPU
epoch
Model epoch to load; defaults to 0

def classify(input: IndexedSeq[Array[Float]], topK: Option[Int] = None): IndexedSeq[(String, Float)]

Takes flat arrays as input and returns (Label, Score) tuples.
Takes flat arrays as input and returns (Label, Score) tuples.
input
