Installation process for facial recognition dependancies

fr_deps.md

Step 1: Install dependancies

sudo apt -y update && sudo apt -y full-upgrade
sudo apt install build-essential \
    cmake \
    gfortran \
    git \
    wget \
    curl \
    graphicsmagick \
    libgraphicsmagick1-dev \
    libatlas-base-dev \
    libavcodec-dev \
    libavformat-dev \
    libboost-all-dev \
    libgtk2.0-dev \
    libjpeg-dev \
    liblapack-dev \
    libswscale-dev \
    pkg-config \
    python3-dev \
    python3-numpy \
    python3-pip \
    zip \
    python3-picamera

Step 2: Updates

sudo pip3 install --upgrade picamera[array]

Step 3: Increase the swap file size so we can build dlib

sudo nano /etc/dphys-swapfile

Find CONF_SWAPSIZE and change its value from 100 to 1024. Save and exit then run this command:

sudo /etc/init.d/dphys-swapfile restart

Step 4: Build and install dlib

cd
git clone -b 'v19.6' --single-branch https://github.com/davisking/dlib.git
cd ./dlib
sudo python3 setup.py install --compiler-flags "-mfpu=neon"

This may take a significant time to run (Raspberry Pi 4 took about 30 minutes)

Step 5: Revert the swap size

sudo nano /etc/dphys-swapfile

Find CONF_SWAPSIZE and change its value from 1024 to 100. Save and exit then run this command:

sudo /etc/init.d/dphys-swapfile restart

Step 6: Install face_recognition and examples

sudo pip3 install face_recognition

You're done!

Hi there I am very much unfamiliar with what I am doing. Trying to nab these dependencies for a facial recognition project as recommended by the raspberry pi hackspace tutorial. Im getting several errors running the first command in the raspberry pi terminal: "Package [cmake/libgtk2.0-dev/gfortran] is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source". Then it goes on to say that several packages either have no installation candidate or cannot be located. Any comments/recommendations?

Sorry to hear this. I'll have to go through and try and find out what's changed.

Apologies for my delay in responding. I've tested this now and an initial step is missing. Before running the huge install command, make sure you run...

sudo apt -y update && sudo apt -y full-upgrade

This will ensure your repositories are up-to-date.

Thank you so much! I will try this out

I got up to stage 4 with this. When running the line "sudo python3 setup..." it said
running install running bdist_egg running build error: Cannot find cmake, ensure it is installed and in the path. You can install cmake using the instructions at https://cmake.org/install/ You can also specify its path with --cmake parameter

I will try messing around with it for a bit

Try
sudo apt install build-essential
Then try again

Also stucked on step 4, says "no module named 'distro' in the error message when running "sudo python3 setup.py install..." line.
Tried to install distro package but still doesn't work.
Messing around right now

You need to install it as root, so...
sudo pip3 install distro

Thank you so much for the help so far! I ran the "sudo apt install build-essential" line before the rest but at the fourth step I came up with the same error at the end. At "sudo nano /etc/dphys-swapfile" I assume I am saving correctly because I saw the changed value I made the first time around but perhaps I am still making a mistake somehow, somewhere

Try explicitly installing cmake:
sudo apt install cmake
And try again

I got farther but a bunch of warnings and errors popped up. At the end it says Boost python library was not found and cmake configuration failed

I am also stuck at step 4 with the sudo python3 setup.py install --compiler-flags "-mfpu=neon" command.
I am getting an AttributeError: 'Thread' object has no attribute 'isAlive'
Any assistance would be appreciated.

Should there be an additional \ in the second-to-last line of the install step, ie:

python3-pip \
zip
python3-picamera

Should be

python3-pip \
zip \
python3-picamera

Thanks for pointing that out mr-douglas

@DillonMcCardell did you ever get past the 'Thread' object has no attribute 'isAlive' error? I am stuck there as well.

@polyphonic13 Try step 4 but omit

-b 'v19.6'

From the git clone command.

@DillonMcCardell thanks for the response. I ended up using a different solution and got it working. Go to know you fixed yours though!
