PyTorch is a production ready, open source machine learning framework for accelerating AI research prototyping and production deployment. PyTorch is used by countless users in the AI and Deep Learning industry including big commercial names like Amazon and well known universities like Stanford.
Capabilities & Features
Transition seamlessly between eager and graph modes with TorchScript, and accelerate the path to production with TorchServe.
Scalable distributed training and performance optimization in research and production is enabled by the torch.distributed backend.
A rich ecosystem of tools and libraries extends PyTorch and supports development in computer vision, NLP and more.
Why Use PyTorch for Deep Learning?
PyTorch is extremely powerful for creating computational graphs. Compared to Tensorflow's static graph, PyTorch believes in a dynamic graph. Instead of first having to define the entire computation graph of the model before running your model (as in Tensorflow), in PyTorch, you can define and manipulate your graph on-the-fly. This feature is what makes PyTorch an extremely powerful tool for researchers, particularly when developing Recurrent Neural Networks (RNNs).
