Filling c++ arrays with each row of a 2D tensor

C++
1

If I am trying to dump each row of a 2D tensor into an array in C++, is this appropriate?

array<float, 3> data;

float *values_ptr = &tensor_data.data_ptr<float>()[i * tensor_data.stride(1)]
for (int i=0; i < 3; i++) {
	data[i] = values_ptr[i];
}

Or is there a faster or more memory-efficient way to do this?
