* rewriting base file to get ride of numpy matrices. * last modification to rewrite into full numpy integration * rewriting mean with dotted notation and getting rid of numpy matrices * continuing to rewrite the geodesic * rewriting of the spatial filters * small style correction in channelselection * updating the use of numpy for all higher packages * last rewriting of pyriemann file * adding slack notification * finishing to update numpy ref and removing numpy matrices * covering all functions of classification: TSclassifier, kNN * PEP8 conformation for test clustering * PEP 8 normalisation * fixing last bugs for testing * update test * adding test for Potato * end of modification of test units and coverage improvment. * modifying and adapting travis file. * updating travis file and correcting error in testing wasserstein mean * adding pandas in the requierement for Travis * ajout de la generation de matrice SPD * Correcting the Karcher mean implementation if the gradient descent is initialized on one of the point of the set, generating zero-divide error. * adding ALM to mean computation * adding ref for the parametrized geodesic * update avant merge * uncomplete merge * merge with upstream * use fixture and parametrize for tests, avoid code redundancy, systematic test of dist and metric * correct tangent fit bug Co-authored-by: kjersbry <noreply@github.com> Co-authored-by: sylvchev <noreply@github.com> * add tsupdate check * reduce complexity of the test to make them faster * add flake8 to tests and examples, correct style in tests * switch to triangular inequality to avoid random failure * update coverage * remove redundant tests, add coverage * correct flake8 * correct F401,F811 import errors with fixtures * correct w value * remove assert_array_equal and correct variable names Co-authored-by: Quentin Barthélemy <q.barthelemy@gmail.com> * add is_spsd and get_labels fixture * adding test for Schaefer estimator * update test
