T’s runtime is based around a stack machine, all operators pop off arguments from the stack, pass them to
some implementation of the operator then push results back onto the stack. The actual elements of the stack
are
          <code class="docutils literal notranslate">
           <span class="pre">
            torch::jit::IValues
           </span>
          </code>
          , the same type we evaluate in the conversion phase (the realization of the abstract
torch::jit::Value type).
