Hello all,
This is my first time here and I am working on issue #28823. I found a
mistake in the implementation of _flatten function in array_expressions.py
and I believe that I have fixed it. I just wanted to confirm my
understanding of what the _flatten function was intended to do, before
submitting a PR.
Are ArrayDiagonal(A, (2, 6), (3, 7), (0, 5), (1, 5)) and
ArrayDiagonal(ArrayDiagonal(A, (2, 6), (3, 7)), (0, 3), (1, 5)) equivalent
where the first one is got after flattening of second one? where
A = ArraySymbol("A", (1, 1, 1, 1, 1, 1, 1, 1)).
My understanding is that while removing the nesting it should also remap
the axes indices. Can anyone confirm it? Also are there test cases for
these operations?
Thank you
