## Preparations

### Back-up the local BASH configuration file
cp $HOME/.bashrc $HOME/.bashrc.backup

## Install dependencies

### Check Ubuntu version
UBUNTU_VERSION=$( lsb_release -r | awk '{ print $2 }' )

### Install dependencies depending on the version of Ubuntu
if [[ "$UBUNTU_VERSION" == "16.04" ]]; then
  install_system_deps_ubuntu_1604
else
  echo "Error: Unknown or unsupported Linux distribution."
  exit

### Install common Python dependencies
install_python_deps

## Install DeepTAM

### Add environment variable for DEEPTAM_ROOT
DEEPTAM_ROOT="$( cd "$( dirname "${BASH_SOURCE[0]}" )" >/dev/null 2>&1 && pwd )"
sed -i "/\b\DEEPTAM_ROOT\\b/d" $HOME/.bashrc
printf 'export DEEPTAM_ROOT='$DEEPTAM_ROOT'\n' >> $HOME/.bashrc

### Install the python-packages
cd $DEEPTAM_ROOT
pip install -e .

### Install the lmbdspecial ops submodule
git submodule init
git submodule update
LMBSPECIALOPS_ROOT=$DEEPTAM_ROOT/lib/lmbspecialops
cd $LMBSPECIALOPS_ROOT
#### build the submodule
mkdir build
