Error on line 1: The fate of Lehman Brothers, the beleaguered investment bank, hung in the balance on Sunday as Federal Reserve officials and the leaders of major financial institutions continued to gather in emergency meetings trying to complete a plan to rescue the stricken bank. Several possible plans emerged from the talks, held at the Federal Reserve Bank of New York and led by Timothy R. Geithner, the president of the New York Fed, and Treasury Secretary Henry M. Paulson Jr.

这是错误堆栈:
{{1}}
所以不确定接下来该做什么。任何其他组合。
答案 0 :(得分:1)
在序列化步骤中,您使用以下序列进行序列化:
edu.stanford.nlp.ie.NERClassifierCombiner
在加载步骤中,您将加载:
edu.stanford.nlp.ie.crf.CRFClassifier
所以在第二个命令中,使用edu.stanford.nlp.ie.NERClassifierCombiner而错误应该消失。您序列化了NERClassifierCombiner,但正在尝试将其作为CRFC分类器加载。如果您有任何其他麻烦,请告诉我!
答案 1 :(得分:0)
需要先将第二个文件c2is2r3.txt转换为tsv文件,然后将其传递给您的命令。
您可以将O(如果您不确定或想要节省手动标记的时间)与生成的所有令牌相关联,然后使用您的模型进行测试。
