Web29 apr. 2016 · This is a pretty common beginner's mistake with Keras. Unlike other Deep Learning frameworks, Keras does not use integer labels for the usual crossentropy loss, instead it expects a binary vector (called "one-hot"), where the vector is just 0's and a 1 over the index of the right class. WebThis notebook uses keras, a high-level API to build and train models in TensorFlow, and TensorFlow hub, a library for loading trained models from TFHub in a single line of code.
