+The input to the circuit should be a tensor with as size the number of input literals.
 Note that when using the :code:`log` semiring, the inputs are log-probabilities, while in the :code:`real` or :code:`mpe` semiring the inputs should be probabilities.
 In case you are using a probabilistic circuit, you should likely have some input distributions producing these (log-)probabilities prior to the circuit.
