Pointer Arithmetic w/ STDVector/Array of Torch Tensors of Different Dimensions

C++
1

Can I create a vector or array of Torch tensors with differing dimensions as long as they have the same data type? I want to use pointer arithmetic to access the tensors.

Yes, std::vector<Tensor> is a standard thing and also used in PyTorch itself for representing lists of tensors. When passing stuff around, the TensorList, an ArrayRef to Tensor often comes in handy.

Best regards

So if I push a tensor of dim 2x20x200 into the std::vector vector then later I push a tensor of dim 999x999x999 into it, there will be no issues?

After a few 4GB tensors (assuming 32 bit values), you might run out of memory, but other than that, yes, it works.
