This workflow trains a simple convolutional neural network (CNN) on the MNIST dataset via TensorFlow. In order to run the example, please make sure you have the following KNIME extensions installed: * KNIME Deep Learning - TensorFlow Integration (Labs) * KNIME Image Processing (Community Contributions Trusted) * KNIME Image Processing - Deep Learning Extension (Community Contributions Trusted) You also need a local Python installation that includes TensorFlow. Please refer to https://www.knime.com/deeplearning/tensorflow for installation recommendations and further information.
