Your "Hello World" example is giving the following error:

(venv) timothysmith@MacBook-Pro auto % /Volumes/Storage/python/auto/venv/bin/python /Volumes/Storage/python/auto/ai.py
/Volumes/Storage/python/auto/ai.py:16: SyntaxWarning: invalid escape sequence '\d'
  output_transform = lf.transforms.Match('\d+').to_int()
Traceback (most recent call last):

    class NumericAnswerExtractor(lf.LangFunc):

    output_transform = lf.transforms.Match('\d+').to_int()

I tried both:

pip install langfun

and

pip install langfun --pre
