This was always a +bit problematical for arrays that were both f_contiguous and c_contiguous +because c_contiguous took precendence. Relaxed stride checking results in +more such dual contiguous arrays and breaks some existing code as a result. +Note that this also affects changing the dtype by assigning to the dtype +attribute of an array. The aim of this deprecation is to restrict views to +c_contiguous arrays at some future time. A work around that is backward +compatible is to use `a.T.view(...).T` instead. A parameter will also be +added to the view method to explicitly ask for Fortran order views, but +that will not be backward compatible. |
