## README

# C++/CUDA Extensions in PyTorch

An example of writing a C++/CUDA extension for PyTorch. See
[here](https://pytorch.org/tutorials/advanced/cpp_custom_ops.html) for the accompanying tutorial.
This repo demonstrates how to write an example `extension_cpp.ops.mymuladd`
custom op that has both custom CPU and CUDA kernels.

The examples in this repo work with PyTorch 2.4+.

To build:
```
pip install --no-build-isolation -e .
```

To test:
```
python test/test_extension.py
```
