I am looking for something that would work for stride tricks too. Essentially, any possible view. > On 31 Aug 2023, at 23:03, Aaron Meurer wrote: > > In principle this can be reconstructed from the strides, shape, and > base memory address (a.ctypes.data) of the view and base arrays. > However,

[Numpy-discussion] Re: Find location of slice in it's base

In principle this can be reconstructed from the strides, shape, and base memory address (a.ctypes.data) of the view and base arrays. However, not all views can be reconstructed using slices alone, for example, views from reshape operations or stride tricks. I don't know if it's possible to just con
