Debug

Known issues

gotchaThis package only provides the compiled shared library (libnvcomp.so) for CUDA 12. It does not include Python bindings; you must use ctypes, cffi, or a higher-level library like cuPy or RAPIDS.

fix

Install a Python wrapper (e.g., `nvcomp` from NVIDIA or use ctypes directly).

affects: all

gotchaThe library is version-specific to CUDA 12. If you are using a different CUDA version (e.g., 11.x), this package will not work and may cause runtime errors.

fix

Use the appropriate `nvidia-libnvcomp-cuX` package for your CUDA version, or install the CUDA 12 toolkit.

affects: all

deprecatedSome older APIs in nvcomp are deprecated in version 5.2.0. In particular, the GDeflate API has been superseded by Bitcomp; old function names still exist but may be removed in a future release.

fix

Migrate calls from `nvcompGdeflate*` to `nvcompBitcomp*` functions.

affects: >=5.0.0
