SPORCO-CUDA provides GPU-accelerated versions of selected convolutional sparse coding algorithms in the SPORCO <https://github.com/bwohlberg/sporco> package. It is a component of SPORCO, and is subject to the same license, but is made available as an optional extension to avoid complicating the prerequisites and build/install procedure for the main part of SPORCO. If you use this software for published work, please cite it <http://sporco.readthedocs.io/en/latest/overview.html#citing>.
Documentation is available online at Read the Docs <http://sporco-cuda.rtfd.io/>_, or can be built from the root directory of the source distribution by the command
::
python setup.py build_sphinx
in which case the HTML documentation can be found in the build/sphinx/html directory (the top-level document is index.html).
Scripts illustrating usage of the package can be found in the examples directory of the source distribution. These examples can be run from the root directory of the package by, for example
::
python examples/cmp_cbpdn.py
To run these scripts prior to installing the package, it is necessary to build it in place, which involves the following steps:
Install the requirements described below
If nvcc is not already in the executable search path, add it; e.g
::
export PATH=$PATH:/usr/local/cuda-10.1/bin
where /usr/local/cuda-10.1/bin is the path for CUDA compiler nvcc.
Build the sporco-cuda package in place:
::
python setup.py build_ext --inplace
Set the PYTHONPATH environment variable to include the root directory of the package. For example, in a bash shell
::
export PYTHONPATH=$PYTHONPATH:pwd
from the root directory of the package.
If the sporco package is not installed, create a symlink from the SPORCO-CUDA package root directory to the sporco directory in the SPORCO package.
The primary requirements are Python, sporco <https://github.com/bwohlberg/sporco>_ and its requirements, Cython <http://cython.org/>, and the CUDA Toolkit <https://developer.nvidia.com/cuda-toolkit>_.
See the installation instructions <http://sporco-cuda.rtfd.io/en/latest/install.html> in the online documentation <http://sporco-cuda.rtfd.io/>.
SPORCO-CUDA is part of the SPORCO <https://github.com/bwohlberg/sporco>__ package and is distributed with the same 3-Clause BSD license; see the LICENSE file for details.
