2023-02-23[WIP] Wasserstein distance on the circle and Spherical Sliced-Wasserstein (#434)Clément Bonet
* W circle + SSW * Tests + Example SSW_1 * Example Wasserstein Circle + Tests * Wasserstein on the circle wrt Unif * Example SSW unif * pep8 * np.linalg.qr for numpy < 1.22 by batch + add python3.11 to tests * np qr * rm test python 3.11 * update names, tests, backend transpose * Comment error batchs * semidiscrete_wasserstein2_unif_circle example * torch permute method instead of torch.permute for previous versions * update comments and doc * doc wasserstein circle model as [0,1[ * Added ot.utils.get_coordinate_circle to get coordinates on the circle in turn
2022-03-24[MRG] Domain adaptation and unbalanced solvers with backend support (#343)Nathan Cassereau
* First draft * Add matrix inverse and square root to backend * Eigen decomposition for older versions of pytorch (1.8.1 and older) * Corrected eigen decomposition for pytorch 1.8.1 and older * Spectral theorem is a thing * Optimization * small optimization * More functions converted * pep8 * remove a warning and prepare torch meshgrid for future torch release (which will change default indexing) * dots and pep8 * Meshgrid corrected for older version and prepared for future versions changes * New backend functions * Base transport * LinearTransport * All transport classes + pep8 * PR added to release file * Jcpot barycenter test * unbalanced with backend * pep8 * bug solve * test of domain adaptation with backends * solve bug for tic toc & macos * solving scipy deprecation warning * solving scipy deprecation warning attempt2 * solving scipy deprecation warning attempt3 * A warning is triggered when a float->int conversion is detected * bug solve * docs * release file updated * Better handling of float->int conversion in EMD * Corrected test for is_floating_point * docs * release file updated * cupy does not allow implicit cast * fromnumpy * added test * test da tf jax * test unbalanced with no provided histogram * using type_as argument in unif function correctly * pep8 * transport plan cast in emd changed behaviour, now trying to cast as histogram's dtype, defaulting to cost matrix Co-authored-by: Rémi Flamary <remi.flamary@gmail.com>
2021-12-09[MRG] Tensorflow backend & Benchmarker & Myst_parser (#316)Nathan Cassereau
* First batch of tf methods (to be continued) * Second batch of method (yet to debug) * tensorflow for cpu * add tf requirement * pep8 + bug * small changes * attempt to solve pymanopt bug with tf2 * attempt #2 * attempt #3 * attempt 4 * docstring * correct pep8 violation introduced in merge conflicts resolution * attempt 5 * attempt 6 * just a random try * Revert "just a random try" This reverts commit 8223e768bfe33635549fb66cca2267514a60ebbf. * GPU tests for tensorflow * pep8 * attempt to solve issue with m2r2 * Remove transpose backend method * first draft of benchmarker (need to correct time measurement) * prettier bench table * Bitsize and prettier device methods * prettified table bench * Bug corrected (results were mixed up in the final table) * Better perf counter (for GPU support) * pep8 * EMD bench * solve bug if no GPU available * pep8 * warning about tensorflow numpy api being required in the backend.py docstring * Bug solve in backend docstring * not covering code which requires a GPU * Tensorflow gradients manipulation tested * Number of warmup runs is now customizable * typo * Remove some warnings while building docs * Change prettier_device to device_type in backend * Correct JAX mistakes preventing to see the CPU if a GPU is present * Attempt to solve JAX bug in case no GPU is found * Reworked benchmarks order and results storage & clear GPU after usage by benchmark * Add bench to backend docstring * better benchs * remove useless stuff * Better device_type * Now using MYST_PARSER and solving links issue in the README.md / online docs
