MaltParser working in python shell but not in a script:help warmly welcome

[Marco Ippolito]

• Hi everybody,

• I would like to use MaltParser in conjunction with Nltk.

• Bu it happens that the same code works in the python shell, but gives an error message if put in a script:

• >>> import nltk >>> parser = nltk.parse.malt.MaltParser(working_dir="/home/ubuntu/maltparser-1.7.2", mco="engmalt.linear-1.7") >>> txt = "This is a test sentence" >>> graph = parser.raw_parse(txt) >>> graph.tree().pprint() '(This (sentence is a test))'

  MaltPipeline.py: 

  • #!/usr/bin/python

  # Dependency Trees

  import nltk parser = nltk.parse.malt.MaltParser(working_dir="home/ubuntu/maltparser-1.7.2", mco="engmalt.linear-1.7")

  txt = "This a test sentence" graph = parser.raw_parse(txt) graph.tree().pprint()

• 19:48

  python MaltPipeline.py
  

  Traceback (most recent call last): File "MaltPipeline.py", line 9, in <module> graph = parser.raw_parse(txt) File "/usr/local/lib/python2.7/dist-packages/nltk/parse/malt.py", line 111, in raw_parse return self.parse(words, verbose) File "/usr/local/lib/python2.7/dist-packages/nltk/parse/malt.py", line 98, in parse return self.tagged_parse(taggedwords, verbose) File "/usr/local/lib/python2.7/dist-packages/nltk/parse/malt.py", line 131, in tagged_parse delete=False) File "/usr/lib/python2.7/tempfile.py", line 454, in NamedTemporaryFile (fd, name) = _mkstemp_inner(dir, prefix, suffix, flags) File "/usr/lib/python2.7/tempfile.py", line 235, in _mkstemp_inner fd = _os.open(file, flags, 0600) OSError: [Errno 2] No such file or directory: 'home/ubuntu/maltparser-1.7.2/malt_input.conllT4_r6M

Any help is warmly welcome.

Hello,

Look at the difference between the two lines:

• >>> parser = nltk.parse.malt.MaltParser(working_dir="/home/ubuntu/maltparser-1.7.2", mco="engmalt.linear-1.7")
  

• 19:48

  MaltPipeline.py: 

• parser = nltk.parse.malt.MaltParser(working_dir="home/ubuntu/maltparser-1.7.2", mco="engmalt.linear-1.7")

  
  

You are missing / before home.

Dear Sir,

Are you still working wilt MALT  and NLTK?
I started a research project when I have to use Malt Naltk and python to show the dependencies.
I did not find helpful tutorials/codes.

Sincerely
