pycld3

✓ import pycld3

✗ import cld3

The package name on PyPI is pycld3, but the module is imported as pycld3. A common mistake is to import cld3 (which matches the Google library name).

Basic usage of pycld3 to detect language of a string and get top N languages.

import pycld3 # Detect language of a text result = pycld3.classify('This is a test') print(result) # LanguageResult(language='en', probability=0.9999, reliable=True) # Get top N languages results = pycld3.top_n('This is a test', 3) print(results) # [LanguageResult(language='en', ...), ...] # Language identification for multiple texts for text in ['Bonjour', 'Hola', 'Hello']: result = pycld3.classify(text) print(f"{text} -> {result.language}")

Debug

Known issues

breakingPython 3.6+ only: pycld3 0.22 drops support for Python 3.5 and earlier. Import error on older versions.

fix

Use Python 3.6 or newer.

affects: >=0.22

gotchaCheck for reliable flag: The language detection may return a low probability result. Always check the `reliable` boolean attribute before trusting the output.

fix

if not result.reliable: handle uncertain detection.

affects: all

gotchaThread safety: The underlying C library is not thread-safe. Do not call classify or top_n concurrently from multiple threads without locking.

fix

Use locks or single-threaded access.

affects: all

deprecatedThe `cld3` import alias (import cld3) was removed in version 0.22. Use `import pycld3`.

fix

Change import from cld3 to pycld3.

affects: >=0.22
