spaCy v2.2.2 Release Notes

Release Date: 2019-10-31 // over 4 years ago

  • 🍱 ✨ New features and improvements

    • 🆕 NEW: Support multiprocessing in nlp.pipe via the n_process argument (Python 3 only).
    • 👍 Base language support for Luxembourgish.
    • ➕ Add noun chunks iterator for Swedish.
    • 📜 Retrained models for Greek, Norwegian Bokmål and Lithuanian that now correctly support parser-based sentence segmentation.
    • 📦 Repackaged models for Greek and German with improved lookup tables via spacy-lookups-data.
    • ➕ Add warning in debug-data for low sentences per doc ratio.
    • 👌 Improve checks and errors related to ill-formed IOB input in convert and debug-data CLI.
    • 👌 Support training dict format as JSONL.
    • 👉 Make EntityRuler ID resolution 2× faster and support "id" in patterns to set Token.ent_id.
    • 👌 Improve rendering of named entity spans in displacy for RTL languages.
    • Update Thinc to ditch thinc_gpu_ops for simpler GPU install.
    • 👌 Support Mish activation in spacy pretrain.

    • ➕ Add forwards-compatible support for new Language.disable_pipes API, which will become
      0️⃣ the default in the future. The method can now also take a list of component names as its first argument (instead of a variable number of arguments).

      • disabled = nlp.disable_pipes("tagger", "parser")+ disabled = nlp.disable_pipes(["tagger", "parser"])

    • ➕ Add forwards-compatible support for new Matcher.add and PhraseMatcher.add API, which will become the default in the future. The patterns are now the second argument and a list (instead of a variable number of arguments). The on_match callback becomes an optional keyword argument.

      patterns = [[{"TEXT": "Google"}, {"TEXT": "Now"}], [{"TEXT": "GoogleNow"}]]- matcher.add("GoogleNow", None, *patterns)+ matcher.add("GoogleNow", patterns)- matcher.add("GoogleNow", on_match, *patterns)+ matcher.add("GoogleNow", patterns, on_match=on_match)

    • ➕ Add new and improved tokenization alignment in gold.align behind a feature flag. The new alignment may produce backwards-incompatible results, so it won't be enabled by default before v3.0.

      import spacy.gold spacy.gold.USE_NEW_ALIGN = True

    🍱 ⚠️ Backwards incompatibilities

    • The unused attributes lemma_rules, lemma_index, lemma_exc and lemma_lookup of the Language.Defaults have now been removed to prevent confusion (e.g. if users add rules that then have no effect). The only place lemmatization tables are stored and can be modified at runtime is via nlp.vocab.lookups.

      • nlp.Defaults.lemma_lookup["spaCies"] = "spaCy"+ lemma_lookup = nlp.vocab.lookups.get_table("lemma_lookup")+ lemma_lookup["spaCies"] = "spaCy"
