PYBIND11
Seamless C++11 to Python binding generation
BSD-3-Clause
ABOUT
Writing Python bindings for C++ code traditionally meant hand-authoring CPython extension boilerplate — verbose, error-prone, and painful to maintain across Python versions. pybind11 provides a modern C++11 API with automatic type conversion for STL containers, NumPy arrays, Eigen tensors, and function overloading. A single header include and a few lines of C++ expose any class or function to Python with proper docstrings, exception translation, and iterator protocol support. The result is bindings that compile quickly, run at native speed, and require minimal maintenance.
INSTALL
pip install pybind11INTEGRATION GUIDE
1. Expose high-performance C++ simulation or physics engines to Python with minimal boilerplate and zero runtime overhead
2. Build Python bindings for custom CUDA/C++ GPU kernels used in PyTorch extensions and custom ops
3. Wrap legacy C++ libraries (computer vision, signal processing, serialization) for use in modern Python AI pipelines
4. Create Python interfaces for embedded systems C++ code while retaining control over memory management and lifetime
5. Prototype fast NumPy-compatible C++ extensions with automatic array conversion and shape validation
