[FEA]: Introduce Python module with CCCL headers by rwgk · Pull Request #3201 · NVIDIA/cccl

rwgk · 2024-12-19T19:24:52Z

Description

Factor out cuda-cccl pip-installable package (cccl/python/cuda_cccl) with CCCL headers from cuda-cooperative and cuda-parallel.
- Fixes a bug: pip install works as expected in one pass. Resolves this.
Factor out cuda.cccl.include_paths from cuda.cooperative.experimental._nvrtc and cuda.parallel.experimental._bindings.
Comprehensive pyproject.toml, setup.py modernization in cuda_cccl, cuda_cooperative, cuda_parallel.
os.path -> pathlib modernization in all .py files touched by this PR.
Revise ci/test_python.sh so that cuda_cooperative and cuda_parallel testing is completely independent (they now run in fresh virtual environments).
Add pre-commit TOML format — taplo-pre-commit — TOML lint worked interactively but not in the CCCL CI (see [FEA]: Enable taplo-lint pre-commit #3426).

Currently cuda-cccl is not published on PyPI. For interactive development, this is the recommended workflow:

cd python/cuda_cooperative  # or cuda_parallel
pip install --editable ../cuda_cccl                                                    
pip install --editable .[test]                                                         
pytest -v ./tests/

I.e. by installing cuda-cccl first, the dependency is satisfied when running pip install in cuda_cooperative or cuda_parallel.

However, CI testing (ci/test_python.sh) uses an alternative approach, to ensure that we're not accidentally removing cuda-cccl from the dependencies in {cuda_cooperative,cuda_parallel}/pyproject.toml. Concretely, pip install is only run once, using the pip install --constraint option:

echo 'cuda-cccl @ file:///home/coder/cccl/python/cuda_cccl' > /tmp/cuda-cccl_constraints.txt
pip install --constraint /tmp/cuda-cccl_constraints.txt .[test]

This will fail if cuda-cccl is missing in the dependencies.

Note for completeness:

I spent a significant amount of time trying to use hatchling as the build backend (instead of setuptools):

61637d6

With that commit, pip install worked, but pip install --editable did not. The root cause is this file installed by cuda-python:

https://github.com/NVIDIA/cuda-python/blob/54a93e677b9ba5980dff24c649aa61e004f64416/cuda_bindings/cuda/__init__.py

This file interferes with Python's Implicit Namespace Packages mechanism, which is what hatchling relies on in --editable mode.

pip install --editable does not work (anymore).

Q: In what way is it not working?

pip install --editable does not work (anymore).

Q: In what way is it not working?

It is getting a non-existing path here:

cccl/python/cuda_parallel/cuda/parallel/experimental/_bindings.py

Line 57 in d6253b5

cub_include_path = str(f.parent / "_include")

At HEAD, cuda_paralleld/cuda/_include exists in the source directory (it is .gitignored), but with this PR, that directory no longer exists and the trick/hack I'm using in the code above fails.

Leo: Do you still recommend that we replace shutil.copytree() (in setup.py) with the cmake-based alternative?

I'm asking because that'll take this PR in a very different direction (I think).

Logging an observation (JIC it's useful to reference this later):

With CCCL HEAD (I have @ d6253b5)

TL;DR: pip install for cuda_cooperative or cuda_parallel does not work correctly in the first pass.

@gevtushenko could this explain your "only works 50% of the time" experience?

Current working directory is cccl/python/

deactivate
rm -rf devenv
git clean -fdx cuda_cooperative/ >& /dev/null
python -m venv devenv
. devenv/bin/activate
pip install --verbose ./cuda_cooperative[test] >& ~/pip_install_cuda_cooperative_log1.txt
ls -lR devenv/lib/python3.12/site-packages/cuda/_include | wc -l
pip install --verbose ./cuda_cooperative[test] >& ~/pip_install_cuda_cooperative_log2.txt
ls -lR devenv/lib/python3.12/site-packages/cuda/_include | wc -l

The output is:

ls: cannot access 'devenv/lib/python3.12/site-packages/cuda/_include': No such file or directory

Similarly for cuda_parallel:

deactivate
rm -rf devenv
git clean -fdx cuda_parallel/ >& /dev/null
python -m venv devenv
. devenv/bin/activate
pip install --verbose ./cuda_parallel[test] >& ~/pip_install_cuda_parallel_log1.txt
ls -lR devenv/lib/python3.12/site-packages/cuda/_include | wc -l
pip install --verbose ./cuda_parallel[test] >& ~/pip_install_cuda_parallel_log2.txt
ls -lR devenv/lib/python3.12/site-packages/cuda/_include | wc -l

Same output as above.

rwgk · 2024-12-19T23:32:37Z

Now with this PR (@ daab580)

TL;DR: Same problem (this had me really confused TBH).

deactivate
rm -rf devenv
git clean -fdx cuda_cccl/ >& /dev/null
python -m venv devenv
. devenv/bin/activate
pip install --verbose ./cuda_cccl[test] >& ~/pip_install_cuda_cccl_log1.txt
ls -lR devenv/lib/python3.12/site-packages/cuda/_include | wc -l
pip install --verbose ./cuda_cccl[test] >& ~/pip_install_cuda_cccl_log2.txt
ls -lR devenv/lib/python3.12/site-packages/cuda/_include | wc -l

Output:

Small summary:

pip install cuda_cooperative or cuda_parallel does not work reliably at HEAD.
Simply moving out cuda-cccl does not fix that.
But we have the bigger question: Should I even try to fix that? Or should I instead try to use CMake instead of setuptools?

rwgk · 2024-12-20T00:20:07Z

Commit ef9d5f4 makes the pip install ./cuda_cccl command work reliably.

I wouldn't be surprised if this isn't the right way of doing it, but it does work in one pass.

… cuda._include to find the include path.

rwgk · 2024-12-20T00:57:35Z

Commit bc116dc fixes the pip install --editable issue.

… (they are equivalent to the default functions)

rwgk · 2024-12-20T01:55:53Z

It turns out what I discovered the hard way was actually a known issue:

We're in a good shape now! A few minor comments

leofang · 2025-01-16T18:54:11Z

python/cuda_cooperative/cuda/cooperative/experimental/_nvrtc.py

+    from cuda.cccl import get_include_paths
+
+    for path in get_include_paths().as_tuple():
+        if path:


I think this check should be moved to get_include_paths() so that we only pay this cost once per process? (and I think you've done that check via assert!)

I think it's better to keep the if here, because with the current setup ...

@dataclass class IncludePaths: cuda: Optional[Path] libcudacxx: Optional[Path] cub: Optional[Path] thrust: Optional[Path]

... it's safer. The Optional here are for flexibility/reusability/future-proofing.

Possibly, in the future some of the paths will be None.

I expect the runtime overhead (the price we pay for the flexibility) to be unmeasurable, especially because this function is cached, but even without caching.

However, I changed it to if path is None: (commit 12dbf29), for consistency, after I just realized that that's what we have in python/cuda_parallel/cuda/parallel/experimental/_bindings.py.

-        )
+        for path in get_include_paths().as_tuple()
        if path is not None


ditto, path could be checked only once in get_include_paths()

I don't have a good way to declare version constraint for cuda-cccl statically, I suspect we will need to move dependencies to setup.py's install_requires, let us do this in another PR
