What is the difference between Keras and PyTorch?

Keras and PyTorch differ mainly in their style and purpose. Keras focuses on being easy and simple to use, making it great for beginners and for quickly building models. PyTorch offers more control and lets you change more details, thanks to its flexible dynamic graphs. Researchers and experienced users often prefer PyTorch for experiments. Keras saves time with less code, while PyTorch supports more custom tasks.
