gistfile1.txt

conda uninstall --force pillow -y

# install libjpeg-turbo to $HOME/turbojpeg
git clone https://github.com/libjpeg-turbo/libjpeg-turbo
pushd libjpeg-turbo
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX:PATH=$HOME/turbojpeg
make
make install
popd

# install pillow-simd with jpeg-turbo support
git clone https://github.com/uploadcare/pillow-simd
pushd pillow-simd
CPATH=$HOME/turbojpeg/include LIBRARY_PATH=$HOME/turbojpeg/lib CC="cc -mavx2" python setup.py install

# add turbojpeg to LD_LIBRARY_PATH
export LD_LIBRARY_PATH="$HOME/turbojpeg/lib:$LD_LIBRARY_PATH"

I also had to install zlib:

sudo apt install zlib1g-dev
