Pi Setup

The following takes you through how to setup the Raspberry pi. We're assuming your Pi is connected to a wifi network and you are able to ssh into the Pi from your PC. If you have a new Pi and you need to set this up. Please checkout the Donkeycar wiki and complete up to step 9. Donkeycar Wiki

1. Install python3.6

wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tar.xz
tar xf Python-3.6.5.tar.xz
cd Python-3.6.5
./configure
make
sudo make altinstall

# Enter...and...agree

conda config --add channels rpi
conda install python=3.6

cd ~
sudo apt-get remove python-pip python3-pip
wget https://bootstrap.pypa.io/get-pip.py
python3 get-pip.py
python3 -m venv dingo
source ~/dingo/bin/activate
pip install -e.[pi]     # This can takea while because it 
                        # needs to build pandas from source
                        # It took +1h for me :-(
pip install tensorflow==1.14

#### ONLY DO THIS IF:
# This fails with an error that looks something like:
