Documentation

CharonLoad is a bridge between Python code and rapidly developed custom C++/CUDA extensions to make writing **high-performance research code** with *PyTorch* easy:

- 🔥 PyTorch C++ API detection and linking
- 🔨 Automatic just-in-time (JIT) compilation of the C++/CUDA part
- 📦 Cached incremental builds and automatic clean builds
- 🔗 Full power of CMake for handling C++ dependencies
- ⌨️ Python stub file generation for syntax highlighting and auto-completion in VS Code
- 🐛 Interactive mixed Python/C++ debugging support in VS Code via *Python C++ Debugger* extension

CharonLoad reduces the burden to start writing and experimenting with custom GPU kernels in PyTorch by getting complex boilerplate code and common pitfalls out of your way. Developing C++/CUDA code with CharonLoad feels similar to writing Python scripts and lets you follow the same familiar workflow.

## Installation

CharonLoad requires **Python >=3.9** and can be installed from PyPI:

```sh
pip install charonload
```

## Quick Start

CharonLoad only requires minimal changes to existing projects. In particular, a small configuration of the C++/CUDA project is added in the Python part while the CMake and C++ part should adopt some predefined functions:

- `/main.py`

```python
import charonload

VSCODE_STUBS_DIRECTORY = pathlib.Path(__file__).parent / "typings"

charonload.module_config["my_cpp_cuda_ext"] = charonload.Config(
project_directory=pathlib.Path(__file__).parent / "",
build_directory="custom/build/directory", # optional
stubs_directory=VSCODE_STUBS_DIRECTORY, # optional
)

import other_module
```

- `/other_module.py`

```python
import my_cpp_cuda_ext # JIT compiles and loads the extension

tensor_from_ext = my_cpp_cuda_ext.generate_tensor()
```

- `//CMakeLists.txt`

```cmake
find_package(charonload)

if(charonload_FOUND)
charonload_add_torch_library(${TORCH_EXTENSION_NAME} MODULE)

target_sources(${TORCH_EXTENSION_NAME} PRIVATE src/.cpp)
# Further properties, e.g. link against other 3rd-party libraries, etc.
# ...
endif()
```

- ``//src/.cpp``

```cpp
#include

torch::Tensor generate_tensor(); // Implemented somewhere in

PYBIND11_MODULE(TORCH_EXTENSION_NAME, m)
{
m.def("generate_tensor", &generate_tensor, "Optional Python docstring");
}
```
