t.draw()… is not working could someone help me fix this problem please.

[Robel Gedam]

So I typed in the code below and I am getting the error --------"IOError: No such file or directory: u'/Users/rino/nltk_data/corpora/treebank/combined/wsj_001.mrg'

I commented out everything below the second import command and the top part of the code seems to be working just fine…

I don't know why my tree is not drawing out, if someone could please explain I'd appreciate it very much…

Sincerely... Thank you for you time.

import nltk

sentence="i love you, so much"

tokens=nltk.word_tokenize(sentence)

print (tokens)

tagged=nltk.pos_tag(tokens)

print tagged[:]

entities=nltk.chunk.ne_chunk(tagged)

print (entities)

'''from nltk.corpus import treebank

t=treebank.parsed_sents('wsj_001.mrg')[0]

t.draw'''

[Antonio Guerrieri]

Try one more 0 in file name:

t=treebank.parsed_sents('wsj_0001.mrg')[0] 

Cheers

You have "print t.draw" in your code and you can see in the output "<bound method Tree.dray of ...>" which indicates that draw needs to be called as a method. Use

t.draw()

and it should work.

Robel -- you need to call the draw method, i.e. t.draw().
Don't use print().

I tried that and it didn't work… surprisingly though, it did the same thing… its like its not finishing the program & throwing an error.

[Robel Gedam]

Hey thanks for your reply. I just ran ran it as just t.draw() & it printed out whats below but still no tree…

['i', 'love', 'you', ',', 'so', 'much']

[('i', 'PRP'), ('love', 'VBP'), ('you', 'PRP'), (',', ','), ('so', 'RB'), ('much', 'RB')]

(S i/PRP love/VBP you/PRP ,/, so/RB much/RB)

[Robel Gedam]

Changed it and still no tree

[Steven Bird]

Robel, note that the tree is displayed in another window. Python uses
the Tkinter library for drawing trees. Please see the instructions in
the following page to test whether Tkinter is working on your machine:

Import the library and call draw_trees

Incase if it gives error on the import then 

import nltk and then 

nltk.download('maxent_treebank_pos_tagger')

nltk.download('treebank')

from nltk.draw.tree import draw_trees

draw_trees(entities)

This ideally show solve your problem.
