Hi,
currently xtensor python brings seamless integration ofxarray andxtensor types with numpy. Howeverxtensor_fixed type is not supported. Hence the following definitions work (withm an instance ofpybind11::module):
m.def("test_xarray", [](){return xt::xarray<int>{1,2};});m.def("test_xtensor", [](){return xt::xtensor<int, 1>{1,2};});while this one fails
m.def("test_xtensor_fixed", [](){return xt::xtensor_fixed <int, xt::xshape<2>>{1,2};});at runtime. When trying to call the method from python, the following error is reported:
TypeError: Unable to convert function return value to a Python type! The signature was() -> xt::xfixed_container<int, xt::fixed_shape<2ul>, (xt::layout_type)1, xt::xtensor_expression_tag>Would it be possible to add seamless integration withxtensor_fixed ?
