NLTK reuters datasets not found

Question

I downloaded Reuters dataset from nltk using the following command:

import nltk
nltk.download('reuters')

I got a confirmation that the datset was downloaded and I can see the it under "C:/Users/username/AppData/Roaming/nltk_data".

However, when I want to read the dataset, python can't see it! I get the following error:

C:\Users\username\python\Python37-32\Lib\site-packages\sklearn\externals\joblib\externals\cloudpickle\cloudpickle.py:47: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses

I tried to create manually a directory "C:/Users/username/nltk_data" and paste the reuters.zip there, but that didn't help! When I download it again using nltk.download(), it shows me the following:

[nltk_data] Downloading package reuters to C:\Users\username/nltk_data...
[nltk_data]   Package reuters is already up-to-date!

Any hints? I also wondering why the paths printed by python contain slashes /and backslashes \ at the same time?

Answer 1

Since imp module is deprecated while using nltk with python 3.7, use import importlib instead of import imp, or try to run code with older version of python.

Answer 2

this is my code. You can get help accordingly

import nltk
#nltk.download('punkt')
#nltk.download('averaged_perceptron_tagger')
var = open("e:\Assignment\my_file.txt","r") #open file
lines = var.read() #read all lines
sentences = nltk.sent_tokenize(lines) #tokenize sentences
nouns = [] #empty to array to hold all nouns

for sentence in sentences:
     for word,pos in nltk.pos_tag(nltk.word_tokenize(str(sentence))):
         if (pos == 'NN' or pos == 'NNP' or pos == 'NNS' or pos == 'NNPS'):
             nouns.append(word)


print (nouns)

Answer 3

In my case I just to go to a folder where corpus is downloaded and just unzip an archive. To see where corpus was downloaded:

nltk.download('reuters')

[nltk_data] Downloading package reuters to /home/denys/nltk_data...
[nltk_data] Package reuters is already up-to-date!
