Torch7 is a scientific computing framework with a fast multi-dimensional tensor library and math operations, originally built for Lua with a C backend (TH, THNN, THC). It was the predecessor to PyTorch and is no longer in active development, with its functionality rewritten in PyTorch's ATen library.

Use cases

• train neural networks with Lua
• multi-dimensional tensor math operations
• run legacy Torch7 machine learning models
• GPU-accelerated tensor computations with cutorch
• maintain old research codebases built on Torch
• serialize and deserialize arbitrary objects for ML pipelines

When to choose

• you must run or maintain an existing Torch7/Lua codebase
• you need to reproduce results from older research papers that used Torch

When to avoid

• starting any new machine learning project
• you want GPU support, sparse tensors, or modern features - use PyTorch instead
• you need community support or recent updates
