No. A communist society is stateless and classless. If there is a dictatorship, even a dictatorship of the proletariat, it is by definition not communist, and no educated Marxist would argue otherwise. However, we do have another term for the transition state between capitalism and communism where it is possible to have dictatorships - Socialism. (And Leninists would argue that a dictatorship of the proletariat is indeed the preferable state of affairs for any socialist state trying to survive in a global capitalist hegemony).
