python - Print Wikipedia Article Title from Gensim WikiCorpus -

-

i believe question easy, i'm new python , think blinding me bit.

i've downloaded wikipedia dump explained under "preparing corpus" here: https://radimrehurek.com/gensim/wiki.html. ran following lines of code:

import gensim  # these next 2 lines take around 16 hours wikidocs = gensim.corpora.wikicorpus.wikicorpus('enwiki-latest-pages-articles.xml.bz2') gensim.corpora.mmcorpus.serialize('wiki_en_vocab200k', wikidocs)

these lines of code taken link above. now, in separate script i've done text analysis. result of text analysis number representing index of particular article in wikidocs corpus. problem, don't know how print out text of article. obvious thing try is:

wikidocs[index_of_article]

but returns error

typeerror: 'wikicorpus' object not support indexing

i've tried few other things i'm stuck. help.

it's not such easy quesion, reason why didn't work wikicorpus isn't iterator, it's class few functions saving , loading. can see functions buy typing wikicorpus. , pressing tab ipython (this shows options tab-completion:

in [8]: wikidocs = gensim.corpora.wikicorpus.wikicorpus. gensim.corpora.wikicorpus.wikicorpus.get_texts    gensim.corpora.wikicorpus.wikicorpus.load         gensim.corpora.wikicorpus.wikicorpus.save_corpus gensim.corpora.wikicorpus.wikicorpus.getstream    gensim.corpora.wikicorpus.wikicorpus.save

it looks want get_texts, return iterator rather list though, (iterators don't directly support indexing either) you'll have use

list(wikidocs.get_texts())[i]

or 

from itertools import islice next(islice(wikidocs.get_texts(),i,i+1))

i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i

Sass watch command compiles .scss files before full sftp upload -

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course,
