KNIME Deep Learning - Classify images using ResNet50

This workflow performs classification on some sample images using the ResNet50 deep learning network architecture, trained on ImageNet, via Keras (TensorFlow).

In order to run the example, please make sure you have the following KNIME extensions installed:

* KNIME Deep Learning - Keras 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 Keras. Please refer to https://www.knime.com/deeplearning#keras for installation recommendations and further information.
