Deep learning in Python: how to choose a framework?
summary
A practical comparison of deep learning frameworks (PyTorch, TensorFlow/Keras, JAX, MXNet) using a multiclass classification example on Amazon reviews (six labels) implemented with token indices, an embedding layer, one ReLU hidden layer and softmax. PyTorch emphasizes eager execution and manual training loops with built-in per-class weighting; TensorFlow/Keras offers model.fit, automatic input-shape inference, XLA/TPU support, TensorBoard, TFX and TensorFlow Lite for production; JAX compiles via XLA for high-performance GPU/TPU, and MXNet mixes imperative and symbolic code. The takeaway is to choose based on hardware, deployment requirements and availability of pretrained models (PyTorch for research/debugging, TensorFlow for production/TPU ecosystems).
