int data[] ={1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,9,3,5};
torch::Tensor f = torch::from_blob(data, {64},torch::kInt64);

This needs to be long format. Another thing, when I display f, I don’t see {1,2,3,…} but something else like {12000,14000…}
