2022-06-21[MRG] raise error if mass mismatch in emd2 (#386)clecoz
* Two lines added in the function emd2 to ensure that the distributions have the same mass (same as it already was in the function emd). * The same mass test has been moved inside the function f(b) to be compatible with emd2 with multiple b. * Test added. The function test_emd_dimension_and_mass_mismatch (in test/test_ot.py) has been modified to check for mass mismatch with emd2. * Add PR in releases.md * Merge and add PR in releases.md * Add name in contributors.md * Correction contribution in contributors.md * Move test on mass outside of functions f(b) * Update doc of emd and emd2 Co-authored-by: Camille Le Coz <clecoz@camelot.ipsl.polytechnique.fr> Co-authored-by: Rémi Flamary <remi.flamary@gmail.com>
