Install

Run pip install into user folder directly from OpenNAO OS using ssh

pip install --upgrade --user pip SpeechRecognition gTTs googletrans pygame six urllib3

Put this into your .bashrc file

export PATH=$HOME/.local/bin:$PATH
export PYTHONPATH=$HOME/.local/lib/python2.7/site-packages:$PYTHONPATH

Don't forget to source your new .bashrc by

source .bashrc

Note:

in case gTTs or googletrans throw the following error: 'NoneType' object has no attribute 'group' , it is a recent bug on google side and needs to be fixed by manual edit of the library.

How to install and run python libraries in OpenNAO (Pepper OS)

Install python libraries into user home folder using:

pip install --user

Then link those directly in the python script by:

import sys; sys.path.insert(0, "/home/nao/.local/lib/python2.7/site-packages/")

Some libraries are unable to install using pip (for example pyaudio). These libraries are dependent on system packages (e.g. portaudio) that cannot be build, because there is no C++ compiler in OpenNAO. The only way around is to run OpenNAO in VirtualBox, install it there and then copy to user folder. More info here:
