执行下面的代码时,我收到的错误如上所述。
我从http://www.cs.unm.edu/~mccune/prover9/download/下载了所需的软件包并进行了配置。但仍然是同样的问题。
我收到此错误:
>>> import nltk
>>> dt = nltk.DiscourseTester(['A student dances', 'Every student is a person'])
>>> dt.readings()

LookupError:
===========================================================================
NLTK was unable to find the mace4 file!
Use software specific configuration paramaters or set the PROVER9HOME environment variable.
Searched in:
- /usr/local/bin/prover9
- /usr/local/bin/prover9/bin
- /usr/local/bin
- /usr/bin
- /usr/local/prover9
- /usr/local/share/prover9
在通过make all
配置LADR-2009-11时,使用
.o utilities.o provers.o foffer.o ../ladr/libladr.a
search.o: In function `search':
search.c:(.text+0x6e54): undefined reference to `round'
../ladr/libladr.a(avltree.o): In function `avl_item_at_position':

make[1]: *** [prover9] Error 1

答案 0 :(得分:0)
NLTK was unable to find the mace4
和
make: *** [all] Error 2
也许这很明显,但你需要成功构建LADR / Prover9。只有在此之后,您才能使用nltk.Prover9()
或nltk.MaceCommand(...)
那么为什么会出现编译错误?在您的make文件中use gcc flags: -std=c99
and -lm

用户@mircea已经回答了关于Prover9和Mace的类似问题。看看Unable to Open Prover9 and Mace。它是关于设置库的路径,如
prover = nltk.Prover9()
prover.config_prover9(r'd:/prover9/bin')
答案 2 :(得分:0)
我通过修改nltk / inference / prover9.py文件修复了我的问题。在第144行中,定义了binary_locations(self)
我添加了此文件夹的路径:
C:\Program Files (x86)\Prover9-Mace4\bin-win32
(注意:不是证明文件夹,而是bin-win32子文件夹)。在那里,您会找到prover9.exe
和mace4.exe
文件。
最后,我不知道这是否相关,但我下载了这里的GUI:http://www.cs.unm.edu/~mccune/prover9/gui/v05.html。使用Windows 10

今天我遇到了同样的问题。通过将-lm
移动到涉及-lm
的所有行中的行尾来修复它。在Makefile
中修改文件LADR-2009-11A/provers.src
,使其如下所示:
65 prover9: prover9.o $(OBJECTS)
66 $(CC) $(CFLAGS) -o prover9 prover9.o $(OBJECTS) ../ladr/libladr.a -lm
67
68 fof-prover9: fof-prover9.o $(OBJECTS)
69 $(CC) $(CFLAGS) -o fof-prover9 fof-prover9.o $(OBJECTS) ../ladr/libladr.a -lm
70
71 ladr_to_tptp: ladr_to_tptp.o $(OBJECTS)
72 $(CC) $(CFLAGS) -o ladr_to_tptp ladr_to_tptp.o $(OBJECTS) ../ladr/libladr.a -lm
73
74 tptp_to_ladr: tptp_to_ladr.o $(OBJECTS)
75 $(CC) $(CFLAGS) -o tptp_to_ladr tptp_to_ladr.o $(OBJECTS) ../ladr/libladr.a -lm
76
77 autosketches4: autosketches4.o $(OBJECTS)
78 $(CC) $(CFLAGS) -o autosketches4 autosketches4.o $(OBJECTS) ../ladr/libladr.a -lm
79
80 newauto: newauto.o $(OBJECTS)
81 $(CC) $(CFLAGS) -o newauto newauto.o $(OBJECTS) ../ladr/libladr.a -lm
82
83 newsax: newsax.o $(OBJECTS)
84 $(CC) $(CFLAGS) -o newsax newsax.o $(OBJECTS) ../ladr/libladr.a -lm
