Resource u'tokenizers/punkt/english.pickle' not found

Question

My Code:

import nltk.data tokenizer = nltk.data.load('nltk:tokenizers/punkt/english.pickle') 

ERROR Message:

[ec2-user@ip-172-31-31-31 sentiment]$ python mapper_local_v1.0.py Traceback (most recent call last): File "mapper_local_v1.0.py", line 16, in <module>      tokenizer = nltk.data.load('nltk:tokenizers/punkt/english.pickle')  File "/usr/lib/python2.6/site-packages/nltk/data.py", line 774, in load      opened_resource = _open(resource_url)  File "/usr/lib/python2.6/site-packages/nltk/data.py", line 888, in _open      return find(path_, path + ['']).open()  File "/usr/lib/python2.6/site-packages/nltk/data.py", line 618, in find      raise LookupError(resource_not_found)  LookupError:  Resource u'tokenizers/punkt/english.pickle' not found.  Please use the NLTK Downloader to obtain the resource:      >>>nltk.download()  Searched in: - '/home/ec2-user/nltk_data' - '/usr/share/nltk_data' - '/usr/local/share/nltk_data' - '/usr/lib/nltk_data' - '/usr/local/lib/nltk_data' - u'' 

I'm trying to run this program in Unix machine:

As per the error message, I logged into python shell from my unix machine then I used the below commands:

import nltk nltk.download() 

and then I downloaded all the available things using d- down loader and l- list options but still the problem persists.

I tried my best to find the solution in internet but I got the same solution what I did as I mentioned in my above steps.

To add to alvas' answer, you can download only the punkt corpus:

nltk.download('punkt') 

Downloading all sounds like overkill to me. Unless that's what you want.
