Plenty of people have trouble with the syntax of Keras model creation. What’s up with the square brackets? The commas? That weird (x) thing at the end? Without going too deep on a TensorFlow tutorial, I thought I’d share a few things that might help simplify what’s going on. First, it’s important to remember that TensorFlow is based on a graph model. Even though eager execution now allows evaluation of operations immediately, without building graphs, the graph influence is pervasive. I find i…
