3.8.0

3.8.0, 2019-07-08

⚠️ 3.8.x will be the last Gensim version to support Py2.7. Starting with 4.0.0, Gensim will only support Py3.5 and above

🌟 New Features

• Enable online training of Poincare models (koiizukag, #2505)
• Make BM25 more scalable by adding support for generator inputs (saraswatmks, #2479)
• Allow the Gensim dataset / pre-trained model downloader gensim.downloader to run offline, by introducing a local file cache (mpenkov, #2545)
• Make the gensim.downloader target directory configurable (mpenkov, #2456)
• Support fast kNN document similarity search using NMSLIB (masa3141, #2417)

🔴 Bug fixes

• Fix smart_open deprecation warning globally (itayB, #2530)
• Fix AppVeyor issues with Windows and Py2 (mpenkov, #2546)
• Fix topn=0 versus topn=None bug in most_similar, accept topn of any integer type (Witiko, #2497)
• Fix Python version check (charsyam, #2547)
• Fix typo in FastText documentation (Guitaricet, #2518)
• Fix "Market Matrix" to "Matrix Market" typo. (Shooter23, #2513)
• Fix auto-generated hyperlinks in CHANGELOG.md (mpenkov, #2482)

📚 Tutorial and doc improvements

• Generate documentation for the gensim.similarities.termsim module (Witiko, #2485)
• Simplify the Support section in README (piskvorky, #2542)

👍 Improvements

• Pin sklearn version for Py2, because sklearn dropped py2 support (mpenkov, #2510)

⚠️ Deprecations (will be removed in the next major release)

• Remove

  • gensim.models.FastText.load_fasttext_format: use load_facebook_vectors to load embeddings only (faster, less CPU/memory usage, does not support training continuation) and load_facebook_model to load full model (slower, more CPU/memory intensive, supports training continuation)
  • gensim.models.wrappers.fasttext (obsoleted by the new native gensim.models.fasttext implementation)
  • gensim.examples
  • gensim.nosy
  • gensim.scripts.word2vec_standalone
  • gensim.scripts.make_wiki_lemma
  • gensim.scripts.make_wiki_online
  • gensim.scripts.make_wiki_online_lemma
  • gensim.scripts.make_wiki_online_nodebug
  • gensim.scripts.make_wiki (all of these obsoleted by the new native gensim.scripts.segment_wiki implementation)
  • "deprecated" functions and attributes

• Move

  • gensim.scripts.make_wikicorpus ➡ gensim.scripts.make_wiki.py
  • gensim.summarization ➡ gensim.models.summarization
  • gensim.topic_coherence ➡ gensim.models._coherence
  • gensim.utils ➡ gensim.utils.utils (old imports will continue to work)
  • gensim.parsing.* ➡ gensim.utils.text_utils
