可以看下
model.py line 37

            log_likelihood, self.transition_params = tf_ad.text.crf_log_likelihood(logits, label_sequences, text_lens)
            self.transition_params = tf.Variable(self.transition_params, trainable=False)

self.transition_params 可以打印出来,应该会更新的。

这样更新得到的transition_params是每次随机生成的,正确的应该是随着训练过程不断调整的吧?

同问,这里的transition_params是怎么更新的

嗯嗯,发现了,这是一个bug。需要在 crf_log_likelihood 传入 trans 然后进行更新, 已经修改。谢谢提醒
