char rnn classification activation

[siddBanPsu]

In the RNN code here: https://pytorch.org/tutorials/intermediate/char_rnn_classification_tutorial.html,

self.i2h = nn.Linear(input_size + hidden_size, hidden_size)
self.i2o = nn.Linear(input_size + hidden_size, output_size)

there seem to be no activation present, tanh or Relu as is normally seen in RNN's. Why was it done like this for this example?
