PyTorch vs TensorFlow Summary
PyTorch is better for rapid prototyping in research, for hobbyists and for small scale projects. TensorFlow is better for large-scale deployments, especially when cross-platform and embedded deployment is a consideration.
PS. For fast prototyping and tons of available tutorials you may want to try Keras (kerаs.io) too..
