self.net.train()? Is is a valid function?

[ChenYutongTHU]

While reading this code, solver.py, I found in line 431 and line 433 both functions self.net.train() and self.net.eval() are undefined functions, neither defined in model.py or pytorch API. However, no error came out when I did the training. Is there anyone who can enlighten me?
Thanks a bunch

def net_mode(self, train):
        if not isinstance(train, bool):
            raise('Only bool type is supported. True or False')

        if train:
            **self.net.train()**
        else:
            **self.net.eval()**
