hankcs老师好，不好意思打扰了，
我在运行第8章demo_crf_ner.py的时候，训练成功了，但提示错误信息：

iter=202 terr=1.8025141586989235E-4 serr=0.004847447961220416 act=2180584 obj=3557.5335070105125 diff=5.119288864802773E-5
Done!
Traceback (most recent call last):

ner_array = recognizer.recognize(word_array, pos_array) # 序列标注

不知道是哪里的问题？谢谢
