* Added infrastructure for implementation op lu for both cuda and cpu platforms. * Added implementation of helpers with lu op. Signed-off-by: shugeo <sgazeos@gmail.com> * Refactored LU decomposition to use vector of permutations instead. * Refactored helpers for lu op. * Fixed crash with determinant op. * Refactored cpu LU op heleper. * Added implementation for lu op. Signed-off-by: shugeo <sgazeos@gmail.com> * Fixed issue with argmax on column. * Added multithreaded behaviour for lu op helper. * Fixed multithreaded cpu implementation helpers for lu op. * Added cuda implementation for lu op helper. * Finished lu helper implementation for cuda platform. * Eliminated waste prints and comments. * Fixed race condition and multithreading issues. * Fixed memory leak with shape construction. * Corrected test for lu op to avoid near zero elements on the main diagonal." Signed-off-by: shugeo <sgazeos@gmail.com> * Improved test for adjust_constast op. Signed-off-by: shugeo <sgazeos@gmail.com> * Fixed issues with cuda implementation of resize_bicubic helpers.
