- Production deployment needs additional tooling
How to use PyTorch
- Pick OS, package manager and CUDA options on the official site
- Run the generated pip or conda installation command
- Wrap data with Dataset and load it via DataLoader
- Define the network by subclassing torch.nn.Module
- Write the training loop and save the model with torch.save

Alternatives to PyTorch
All in this category
Amp
Built for developers on larger teams needing cross-codebase refactoring, test generation and documentation; overkill for users wanting simple autocomplete or cost-sensitive solo devs. Verification level not recorded ·
Ghostwriter
Best for people already building on Replit or learning to code in the browser; not suitable for developers whose workflow lives in local editors or other IDEs and who need AI help outside the Replit ecosystem. Verification level not recorded ·
