Kerasis an Open Source Neural Network library written in Python that runs on top of Theano or Tensorflow. It is designed to be modular, fast and easy to use. It was developed by François Chollet, a Google engineer. Keras doesn’t handle low-level computation. Instead, it uses another l...

Your custom metric function must operate on Keras internal data structures that may be different depending on the backend used (e.g. tensorflow.python.framework.ops.Tensor when using tensorflow) rather than the raw yhat and y values directly. For this reason, I would recommend using the backend...
