Linalg_norm crash with simple operation

C++
1

The app crash after I call the linarg_norm api, it works fine in python

OS : win10 64bits
libtorch version : 1.9.0 cpu
compiler : vc2019

#include <iostream>
#include <torch/script.h>

int main()
{
    try{
        torch::Tensor input = torch::empty({1, 1, 2});
        torch::linalg_norm(input, 2, -1, true);
    }catch(std::exception const &ex){
        std::cerr<<ex.what()<<std::endl;
    }
}

error message :

exception:Dimension out of range (expected to be in range of [-3, 2], but got 140715421935248)

Any clue how to use this api properly? Thanks
