Hi,

The new addedxt::quantile seems not to play nicely withpytensor.

For me, the following :

xt::pytensor<double,2> arr            {{5.3,4.3,5.3 },             {4.2,4.2,5.2 },             {5.7,4.7,5.7 },             {2.3,4.3,2.3 }};auto q = xt::quantile(arr, {0.3,0.7},1);

raises :

~/xtensor/include/xtensor/xsort.hpp:463:31: error: non-constant-expression cannot be narrowed from type 'xt::xcontainer<xt::pytensor<double, 2, xt::layout_type::dynamic>>::size_type' (aka 'unsigned long') to 'long' in initializer list [-Wc++11-narrowing]
R ev = R::from_shape({de.size()});

I am usingxtl==0.7.5,xtensor==0.24.4,xtensor-python==0.26.1,pybind11==2.10.3.
