splineops 1.0.0

Spline signal processing in N-D with support for GPU computing.

SplineOps: Spline Operations

splineops is a Python-based N-dimensional signal-processing library with support for GPU computing.

Installation

You need at least Python 3.10 to install splineops (ideally Python 3.12). Python 3.11 is also compatible.

Create and activate your Python virtual environment (on Unix or MacOS)

python -m venv splineops-env
source splineops-env/bin/activate

On Windows,

python -m venv splineops-env
.splineops-env/Scripts/Activate

To deactivate the environment use

deactivate

Minimal requirement:

pip install numpy scipy matplotlib

Simply install splineops using pip

pip install splineops

Formatting, Type Checking, and Testing

Formatting and type checking is performed as

tox -e format
tox -e type

The testing requires a valid environment with a supported Python version and tox installed. The tests are run with the following command (automatic pick of the Python version)

tox

The tests can also be launched for a specific Python version (must match the one installed in the active environment)

tox -e py310
tox -e py311
tox -e py312

IMPORTANT: Since CI is not implemented, make sure to run, pass, and/or fix tox -e format, tox -e type, and tox.

Packaging

Using tox (preferred)

tox -e build

Using hatch

hatch build -t wheel

Development Environment

Install splineops development environment in editable mode

pip install -e .[dev]

GPU Compatibility

You can benefit of cupy to deploy splineops. If a specific CUDA version is required, do

pip install cupy cuda-version=12.3

Install splineops cupy development environment in editable mode

pip install -e .[dev_cupy]

Potential other CuPy libraries (CuPy from Conda-Forge)

pip install cupy cutensor cudnn nccl

Building of the Documentation

To build the Sphinx documentation, install splineops doc dependencies

pip install -e .[docs]

Navigate to the docs directory and run the make html command

cd docs
make html

Then, go to docs/_build/html and open index.html to navigate the documentation locally.

Troubleshooting

If you want to make a "clean" build, go to docs and manually delete the folders _build, auto_examples, gen_modules, and the file sg_execution_times.rst. Why isn't this done automatically? Because Sphinx optimizes speed and removes redundant tasks, by not re-creating the examples notebooks if they have already been created. If you, for example, modify the name of the examples files, you will have to delete at least the folder auto_examples. Otherwise, the old examples files will not have disappeared automatically and Sphinx will raise an internal warning referring to a toctree.
