PyTorch TorchScript Guide: Deployment & Optimization

In PyTorch, TorchScript is a tool that converts PyTorch models into serialized scripts. Its main functions include:

1. Deploying across platforms: By converting PyTorch models to TorchScript, it enables models to be deployed in various platforms and environments, including mobile devices, embedded devices, and servers.
2. Performance optimization: TorchScript offers a way to represent models in a static graph, allowing for better optimization and increased model execution efficiency.
3. Model protection: TorchScript can compile PyTorch models into an irreversible binary format to safeguard the intellectual property and trade secrets of the model.
4. Speed up model inference: Models compiled using TorchScript can achieve faster inference speeds, especially when there are a large number of inference requests in a production environment.

In general, TorchScript can assist users in effectively managing and deploying PyTorch models, while also enhancing performance and security.
