【问题描述】：
我正在使用 OpenNLP 1.5.3，我想对英文文本中的位置名称执行 NER。为此，我从下一个 url 下载了相应的模型（en-ner-location.bin）：
http://opennlp.sourceforge.net/models-1.5/
问题在于，当我尝试通过以下命令使用此模型在文本中执行 NER 时：
./Opennlp/bin/opennlp TokenNameFinder en-ner-location.bin < Text.txt > Text.txt.ner_en_loc
我收到以下错误：
Loading Token Name Finder model ... failed
IO error while loading model file 'en-ner-location.bin'
Unexpected end of ZLIB input stream

我的命令有问题还是 OpenNLP 1.5.3 中此模型的错误？
