Installation

Burn Rapberry Pi Lite 64-bit to micro sd card using raspberry pi imager and follow instructions

Configuration And Basic Setting

Using command line to edit config file

sudo raspi-congig

Select fist tab System Options to update wifi setting Select forth tab Localisation Options to update language and timezone Update remote control options upon personal preference with the Interface Options

Note: we will install TeamViewer as our remote control tool, no need to set up vnc here

Using command line to get update

sudo apt-get update
sudo apt-get upgrade

Git

Using command line to install git

sudo apt-get install git

Note: Lite version raspberry pi os doesn't have built-in git command

Python3.10

Before you begin, run a quick update to ensure your system is up-to-date to avoid conflicts during the tutorial and good system maintenance.

sudo su
cd ../../
cd ./etc

sudo apt update && sudo apt upgrade

First off, install the essential dependencies required for building Python 3.10 from source as we shall later see.

sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev wget libbz2-dev

Download the Gzipped source tarball file using the wget command as shown.

sudo wget https://www.python.org/ftp/python/3.10.0/Python-3.10.0.tgz

Now we are ready to install Python 3.10 on Debian 11. First, navigate into the python 3.10 directory.

tar -xvf Python-3.10.0.tgz

Then execute the configure command to confirm if all the dependencies for the installation of Python 3.10 are met.

sudo ./configure --enable-optimizations

To start the build process. Execute the following make command. This takes quite a while, so be patient.

sudo make -j 2

The value ‘2′ represents the number of CPU cores that can be confirmed using the nproc command. Adjust this value according to the number of CPU cores present on your system.

nproc

Finally, run the command below to install python binaries once the build process is complete:

sudo make altinstall

Once the installation is complete, verify that python 3.10 is installed in your machine. Run:

python3.10 --version

run command line to update python alternatives

sudo update-alternatives --install /usr/bin/python python /usr/local/bin/python3.10 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/local/bin/python3.10 1
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.9 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.9 2

python3 --version
python --version

Note: if python version is not 3.1, run command sudo find / -type f -name python3.10 and copy python3.10 path, then run alias python=<PATH> , alias python3=<PATH> , alias pip=<PATH>, and pip3=<PATH>

get python3 pip

sudo apt-get install python3-pip
sudo python3 -m pip install pip --upgrade pip

we may encounter a lsb_release issue here, run command line to edit lsb_release file

sudo nano /usr/bin/lsb_release

edit the first line to the following:

#! /usr/bin/python3.10

Note: more info please refer to this link

install venv

sudo apt-get install python3-venv

Numpy1.22.4

install Numpy1.21.6 in the venv using the command line

pip install numpy==1.22.4

GUI

XFCE4

Turn on your Pi and log in. We will install Xorg. To do this type in:

sudo apt-get install xserver-xorg

If you only install xserver-xorg, you will not have the ability to launch the Xorg Display Server from the command line. This would be a problem if you are not planning on installing a login manager. Otherwise, you do not need to do this. If this is the case, you may want to also install xinit by typing in:

sudo apt-get install xinit

When you install XFCE, some essentials such as settings and file manager are included. By default, XFCE uses XFCE4 Terminal. This is optional to install, however if you choose not to install it, then XTerm will be the default Terminal app.. To install XFCE with XFCE4 Terminal, type in:

sudo apt-get install xfce4 xfce4-terminal

To clean up leftover packages, type in:

sudo apt-get clean

Note: DON'T USE startx YET!!! UNLESS YOU WANT TO SET UP YOUR OWN REMOTE CONTROL.

More info about alternative GUI please refer this link

Apps

highly recommand using these apps to control and edit files on Pi

TeamViewer

I used TV to remote control my Pi, easy setup and doesn't require a monitor A .deb file is a package file designed for the Debian systems package management system. The .deb file is an archive containing all the files that we need for TeamViewer.

wget https://download.teamviewer.com/download/linux/teamviewer-host_armhf.deb

To install the TeamViewer deb package, we will be making use of the dpkg utility which is the base of the Debian package management software.

sudo dpkg -i teamviewer-host_armhf.deb

clean up the mess with the following command

sudo apt --fix-broken install

Connect to Teamviewer with account and password, so that every time Raspberry Pi boit up, it shows in the TeamViewer account's online device list, then could be eaisly connect

sudo teamviewer passwd <PASSWORD>
sudo teamviewer setup

Note: <PASSWORD> must start with number or letter, and must include special character.

use raspi-config to set auto login to GUI

raspi-config

choose System Options and select Boot / Auto Login, then select the last option reboot, and we will be direct to the desktop environment

sudo reboot

After the reboot, we can use TeamViewer to remote control.

Note: Some device needs some customization to the config.txt file from the Raspberry Pi Boot loader to achive proper headless remote control performance. More info please refer to this link

Pi-Apps

I use Pi-Apps to install other apps we need for this project

git clone https://github.com/botspot/pi-apps
~/pi-apps/install

Visual studio code

use pi-apps to instal vs-code on Raspberry-Pi

Chromium

use pi-apps to instal Chromium on Raspberry-Pi

Voice Assistance

Install mycroft as the voice assistance with Coqui TTS YourTTS model

MyCroft

You can find the mycroft-core repo from here

mkdir VA
cd ~/VA
python3 -m venv .
source ./bin/activate
git clone https://github.com/MycroftAI/mycroft-core.git
cd mycroft-core
bash dev_setup.sh
deactivate

Coqui

installing Coqui TTS server in the main directory

cd ./../
mkdir Coqui
cd Coqui
python3 -m venv .
source ./bin/activate

now we enter the venv, we need to set uo the TTS server here

pip install pip --upgrade
pip install tts --upgrade

Note: Only do this if you want customized voice

Find the server.py file under TTS directory by running this line
sudo find ./ -type f -name server.py 
Edit using command
sudo nano <PATH>/server.py
find synthesize.tts(...), add language_name = "en", inside the parante parantesis

Note: if encounter _lzma module not found, run command sudo apt-get install liblzma-dev and pip install backports.lzma, then enter sudo nano /usr/local/lib/python3.10/lzma.py, change line 27 and 28 to ""

initiate the server by running the folowing line

tts-server --model_name tts_models/multilingual/multi-dataset/your_tts --use_cuda=false
