Slice iteration not working with xt::xtensor #2543
Description
xt::xtensor<float_type,3> a = {{{1, 2, 3, 4}, {5, 6, 7, 8}, {9, 10, 11, 12}}, {{13, 14, 15, 16}, {17, 18, 19, 20}, {21, 22, 23, 24}}}; auto a_iter = xt::axis_slice_begin(a, 2u); auto a_end = xt::axis_slice_end(a, 2u); while(a_iter != a_end) { std::cout << *a_iter++ << std::endl; } produces:
{} {} {} {} {} {} while after change from xt::xtensor<float_type,3> to xt::xarray<float_type> produces expected output
