pyrouge元组索引

Question

我试图用pyrouge来计算自动汇总和黄金标准之间的相似性。当它处理两个摘要时，Rouge工作正常。但是当它写出结果时，它会抱怨“元组索引超出范围”有谁知道是什么原因导致了这个问题，以及我如何解决它？

的金标准是BookRags.txt，GradeSaver.txt，GradeSummary.txt，Wikipedia.txt 需要进行比较与为automated.txt
也不应该* .txt或摘要[ a-z0-9A-Z] +工作？但前一个给我“没有重复错误”，后者“元组索引超出范围”的错误

r = Rouge155("D:\ComputerScience\Research\ROUGE-1.5.5\ROUGE-1.5.5") 
r.system_dir = 'D:\ComputerScience\Research\summary\Grendel\\automated' 
r.model_dir = 'D:\ComputerScience\Research\summary\Grendel\manual' 
r.system_filename_pattern = '[a-z0-9A-Z]+.txt' 
r.model_filename_pattern = '[a-z0-9A-Z]+.txt' 
output = r.convert_and_evaluate() 
print(output) 

我手动设置这两个目录。看起来Rouge包可以处理它中的txt。

问题是，流氓图书馆从来没有考虑过你的正则表达式找不到匹配的情况。流氓源代码id = match.groups(0)[0]中的行是有问题的行。如果您在documentation中查看，则表示组功能Return a tuple containing all the subgroups of the match, from 1 up to however many groups are in the pattern...。因为找不到匹配，所以返回一个空元组，并且代码尝试从空元组中获取第一项，这会导致错误。
