python - How to use QThreads with libtorrent in PyQt? -


i want write simple pyqt torrent client, i've got snag that. run loop takes care of downloading files (simple code using libtorrent) in pyqt code. although, when torrent downloading works, ui doesn't show , when change order of called functions, ui shows downloading doesn't work. read qthreads it's bit hard me - explain how qthread work , how use libtorrent? here's example of torrent client code:

import libtorrent lt import time import sys  ses = lt.session() ses.listen_on(6881, 6891)  info = lt.torrent_info(sys.argv[1]) h = ses.add_torrent({'ti': info, 'save_path': './'}) print 'starting', h.name()  while (not h.is_seed()):    s = h.status()     state_str = ['queued', 'checking', 'downloading metadata', \       'downloading', 'finished', 'seeding', 'allocating', 'checking fastresume']    print '\r%.2f%% complete (down: %.1f kb/s up: %.1f kb/s peers: %d) %s' % \       (s.progress * 100, s.download_rate / 1000, s.upload_rate / 1000, \       s.num_peers, state_str[s.state]),    sys.stdout.flush()     time.sleep(1)  print h.name(), 'complete'

i imagine qt runs message loop doesn't return until application terminated.

what believe want move loop body (that polls libtorrent status) message handler that's called regularly qt. say, timer function.

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
