 ### Cython Unit Tests
 
 Cython tests are located in `tests/cython` and need to be built. These builds have the same CUDA Toolkit header requirements as [those of cuda.bindings](https://nvidia.github.io/cuda-python/cuda-bindings/latest/install.html#requirements) where the major.minor version must match `cuda.bindings`. To build them:
