TF Generate MNIST

The TF Generate MNIST operator is an extension of the python27 operator. It runs tensorflow code that generates MNIST images to check a previously trained model (loaded from disk).

The resulting program infers the numbers from each handwriting picture, which is based on the MNIST example https://www.tensorflow.org/tutorials/layersInformation published on non-SAP site.

Prerequisites

  • MNIST model (type binary, default: None): A pretrained MNIST model (including metadata) that was created with the experimental.ml.tensorflow.trainMnist operator (that is, artifacts prefixed with "model.ckpt" that were created with a tf.train.Saver in the repository under modeldir).

  • MNIST image (type binary, default: None): An input stream of MNIST png- or jpg- images in the correct pixel size (28x28).
