pip install -r requirements.txt fails on Windows

I've become this error:

I need help to fix it, thanks.

You're missing swig.exe, so install that however it's done on Windows. There are probably other missing system dependencies, but this hasn't been mapped/documented.

Added some notes to https://github.com/openassistant/oa-core/wiki/Installation#windows

This is the same kind of problem as #22

Closing this issue for now..

The problem here is python's pocketsphinx. I tried the installation process with Python 3.9a, 3.8-stable and 3.7.x on conda. I encountered the same problem and it finally leads to the problem that pocketsphinx isn't build for python versions above 3.6 (no wheels available).

See bambocher/pocketsphinx-python#49 for reference.

This is not a bug of OA. But it could be documented that:

• You have to use python 3.x up to 3.6 if you want to use pip
• You could compile pocketsphinx yourself (but I have no clue how this is done)
