Question

我编写了以下Python程序，其中包含使用Perl程序计算相似性得分的包装函数lesk_similarity。 GetMAxSim函数从两个synstes中的组合数返回最大相似度分数。

import nltk
from nltk.corpus import wordnet
import subprocess

def lesk_similarity(a,b):
    cmd = ['perl','./sample.pl',a,b]
    proc = subprocess.Popen(cmd,stdout = subprocess.PIPE)
    for line in proc.stdout:
        if 'Similarity' in line:
            similarity = int(line.split('=')[-1])
    return similarity

def getMaxSim(synsets1, synsets2):
    maxSim = None
    for s1 in synsets1:
        for s2 in synsets2:
            sim = lesk_similarity(s1,s2)
            if maxSim == None or maxSim < sim:
                maxSim = sim
                s3 = s1
                s4 = s2

    print s3.definition
    print s4.definition
    return maxSi

ChurchSynsets = wordnet.synsets("church", pos="n")
TempleSynsets = wordnet.synsets("temple", pos="n")
print "create<>make:", getMaxSim(ChurchSynsets, TempleSynsets)

churchSynset和Templesynset包含以下数据：

churchsynset [Synset（'church.n.01'），Synset（'church.n.02'），Synset（'church_service.n.01'），Synset（'church.n.04'）] temple synset [Synset（'temple.n.01'），Synset（'temple.n.02'），Synset（'temple.n.03'），Synset（'synagogue.n.01'）]

运行此代码后出现以下错误：

madhusudan@maddy:~/WordNet-Similarity-2.05/samples$ python test4.py
create<>make:
Traceback (most recent call last):
  File "test4.py", line 40, in <module>
    print "create<>make:", getMaxSim(ChurchSynsets, TempleSynsets)
  File "test4.py", line 17, in getMaxSim
    sim = lesk_similarity(s1,s2)
  File "test4.py", line 7, in lesk_similarity
    proc = subprocess.Popen(cmd,stdout = subprocess.PIPE)
  File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child
    raise child_exception
TypeError: execv() arg 2 must contain only strings

请帮我解决这个问题。

尝试更改此行 cmd = ['perl'，'。/ sample.pl'，a，b]

要 cmd = ['perl'，'。/ sample.pl'，str（a），str（b）]

Subprocess.Popen中的Python程序出错
