The two most widely-used open-source machine learning frameworks for training and building deep learning models are TensorFlow and PyTorch. These frameworks have unique differences in their approach to building and training models. While TensorFlow uses a static graph and declarative programming, which provides better optimization opportunities and allows for distributed training, PyTorch makes use of a dynamic computational graph and imperative programming, which allows for a more flexible and easy debugging process. The choice of frameworks depends on the user's specific needs and preferences. This article looks at the available today.
