How to fill a tensor in C++

Question

I\'m creating a tensor like this:

tensorflow::Tensor a(tensorflow::DT_FLOAT, tensorflow::TensorShape());

I know how to fill a scalar value:

Answer 1

tensorflow::Input::Initializer a({{1, 2}, {3, 4}});

Actually it works in compiling, but errors when running, which shows that a is a tensor with [0] tensorshape. I don't know where is wrong, but my successful way is:

tensorflow::Input::Initializer a({1, 2, 3, 4}, tensorflow::TensorShape({2, 2}));
