Deploy the Python Application

Prerequisites:

• portaudio19-dev (to compile pyaudio)
• git
• python3
• python3-pip
• python3-venv
• libopenjp2-7-dev libtiff5 (pillow)

sudo apt install portaudio19-dev git python3-pip python3 python3-venv libopenjp2-7-dev libtiff5 libatlas-base-dev libhdf5-dev libhdf5-serial-dev python-gobject libharfbuzz-bin libwebp6 libjasper1 libilmbase12 libgstreamer1.0-0 libavcodec-extra57 libavformat57 libopencv-dev libqtgui4 libqt4-test omxplayer

Note that an error in installing omxplayer may occour, ignore that. Furthermore, if you use Ubuntu, packages for libjasper1 may not be found, you can solve this problem with:

sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"

sudo apt update

sudo apt install libjasper1 libjasper-dev

git clone https://github.com/CoderBotOrg/coderbot.git
cd coderbot
python3 -m venv .
source bin/activate
pip3 install -r requirements.txt
python3 init.py

Note that an error about PyAudio, similar to this

is completely normal. Installation will proceed using Running setup.py install for PyAudio ... done. As long as you can see "PyAudio" in the list of "Installing collected packages", everything is good.
