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.
Answers:
The same thing happened to me recently, you just need to download the “punkt” package and it should work.
When you execute “list” (l) after having “downloaded all the available things”, is everything marked like the following line?:
[*] punkt............... Punkt Tokenizer Models
If you see this line with the star, it means you have it, and nltk should be able to load it.
I got the solution:
import nltk
nltk.download()
once the NLTK Downloader starts
d) Download l) List u) Update c) Config h) Help q) Quit
Downloader> d
Download which package (l=list; x=cancel)?
Identifier> punkt
If you’re looking to only download the punkt model:
import nltk
nltk.download('punkt')
If you’re unsure which data/model you need, you can install the popular datasets, models and taggers from NLTK:
import nltk
nltk.download('popular')
With the above command, there is no need to use the GUI to download the datasets.
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.
My issue was that I called nltk.download('all') as the root user, but the process that eventually used nltk was another user who didn’t have access to /root/nltk_data where the content was downloaded.
So I simply recursively copied everything from the download location to one of the paths where NLTK was looking to find it like this:
cp -R /root/nltk_data/ /home/ubuntu/nltk_data
Simple nltk.download() will not solve this issue. I tried the below and it worked for me:
in the nltk folder create a tokenizers folder and copy your punkt folder into tokenizers folder.
This will work.!
the folder structure needs to be as shown in the picture
You need to rearrange your folders
Move your tokenizers folder into nltk_data folder.
This doesn’t work if you have nltk_data folder containing corpora folder containing tokenizers folder
From the shell you can execute:
sudo python -m nltk.downloader punkt
If you want to install the popular NLTK corpora/models:
sudo python -m nltk.downloader popular
If you want to install all NLTK corpora/models:
sudo python -m nltk.downloader all
To list the resources you have downloaded:
python -c 'import os; import nltk; print os.listdir(nltk.data.find("corpora"))'
python -c 'import os; import nltk; print os.listdir(nltk.data.find("tokenizers"))'
Go to python console by typing
$ python
in your terminal. Then, type the following 2 commands in your python shell to install the respective packages:
>> nltk.download(‘punkt’)
>> nltk.download(‘averaged_perceptron_tagger’)
This solved the issue for me.
For me nothing of the above worked, so I just downloaded all the files by hand from the web site http://www.nltk.org/nltk_data/ and I put them also by hand in a file “tokenizers” inside of “nltk_data” folder. Not a pretty solution but still a solution.

Execute the following code:
import nltk
nltk.download()
-
After this, NLTK downloader will pop out.
- Select All packages.
- Download punkt.
import nltk
nltk.download('punkt')
Open the Python prompt and run the above statements.
The sent_tokenize function uses an instance of PunktSentenceTokenizer from the
nltk.tokenize.punkt module. This instance has already been trained and works well for
many European languages. So it knows what punctuation and characters mark the end of a
sentence and the beginning of a new sentence.
I faced same issue. After downloading everything, still ‘punkt’ error was there. I searched package on my windows machine at C:UsersvaibhavAppDataRoamingnltk_datatokenizers and I can see ‘punkt.zip’ present there. I realized that somehow the zip has not been extracted into C:UsersvaibhavAppDataRoamingnltk_datatokenizerspunk.
Once I extracted the zip, it worked like music.
After adding this line of code, the issue will be fixed:
nltk.download('punkt')
Just make sure you are using Jupyter Notebook and in a notebook, do the following:
import nltk
nltk.download()
Then one popup window will appear (showing info https://raw.githubusercontent.com/nltk/nltk_data/gh-pages/index.xml)
From that you have to download everything.
Then rerun your code.
I was getting an error despite importing the following,
import nltk
nltk.download()
but for google colab this solved my issue.
!python3 -c "import nltk; nltk.download('all')"
For me it got solved by using "nltk:"

Failed loading english.pickle with nltk.data.load

Add the following lines into your script. This will automatically download the punkt data.
import nltk
nltk.download('punkt')

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