MacOS

• Install Brew package manager for MacOS

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

• Remove old versions of Python

sudo rm -rf /Library/Frameworks/Python.framework
rm -rf ./Library/Python/

• Install fresh Python 3 and upgrade pip

python3 -m pip install --upgrade pip

• Install univeral Python 3 packages

sudo -H python3 -m pip install --upgrade ipython jupyterlab ipywidgets nbconvert ipykernel autopep8 black yapf isort pipreqs pylint python-language-server[all] genson pipreqs cookiecutter python-dotenv sphinx sphinx-autobuild jsonmerge jupytext pandoc-eqnos pandoc-fignos pandoc-tablenos

• Install pandoc and related useful stuff

brew update
brew install pandoc-citeproc
brew install pandoc-crossref
brew install librsvg

• Install Node.js and NPM

brew install node

• Install MathJax

npm install -g mathjax-node
npm install -g mathjax-node-cli
npm install -g mathjax-pandoc-filter

• Make virtual environment for scipy

python3 -m venv --system-site-packages ./venv/scipy
source venv/scipy/bin/activate

• Install scientific packages into the virtual environment

python3 -m pip install --upgrade scikit-learn scikit-image matplotlib sympy pandas xarray cython tensorly pymc3 nose numexpr Pillow h5py netCDF4 cfunits wpca keras tensorflow pydot statsmodels constrNMPy spectral seaborn dask ipympl pyro-ppl torch torchvision pweave open3d-python trimesh[easy] pyntcloud

• Install libspatialindex for trimesh

brew install spatialindex

• Inspect currently-installed packages

pip freeze > requirements.txt

• Need to install the atmos python package manually and it depends on udunits2

brew install udunits
git clone https://github.com/atmos-python/atmos.git

• Install graphviz -- a dependency for Keras

brew install graphviz

• For Markdown to HTML with LaTeX maths

git clone https://github.com/humenda/GladTeX.git; cd GladTeX; python setup.py install

• Jupyter stuff

jupyter labextension install @jupyter-widgets/jupyterlab-manager
jupyter labextension install jupyter-matplotlib
jupyter labextension install @jupyterlab/toc
jupyter nbextension enable --py widgetsnbextension
jupyter labextension install jupyterlab-jupytext

• Now deactivate the current virtual environment

deactivate

Linux

• Install Ubuntu 18.04.2 LTS

• Install developer tools

sudo apt-get update
sudo apt-get install build-essential cmake unzip pkg-config
sudo apt install python3-pip libssl-dev libffi-dev python3-dev python3-venv
sudo apt-get install git git-gui git-doc

• Install conda

It is useful to install for all users as described here. To do so, install Anaconda in /usr/local/anaconda3. Then do the following:

sudo adduser anaconda
sudo chown -R anaconda:anaconda /opt/anaconda
sudo chmod -R go-w /opt/anaconda
sudo chmod -R go+rX /opt/anaconda
su -c 'printf "# Add anaconda to path\nPATH=$PATH:/usr/local/anaconda3/bin/" >> /home/anaconda/.bashrc' anaconda

• Install dlib

Note there is no conda package

pip3 install dlib --verbose

• Install OpenCV

Tips and Tricks

• Launch a terminal and connect to existing Jupiter environment

jupyter console --existing

• Trick for Atom

{"Python2": "import matplotlib as matplotlib_import_only\nmatplotlib_import_only.use('Agg')\n%matplotlib inline\n%config InlineBackend.figure_format = 'retina'\npython=None"}

• Trick for VSCode

"python.terminal.launchArgs": [
   "-m",
   "IPython",
   "--no-autoindent",
]

• Use this for new data analysis projects

cookiecutter https://github.com/drivendata/cookiecutter-data-science

• Profiling python code (use qcachegrind to view it)

brew install qcachegrind
pprofile --format callgrind --out cachegrind.out.threads python_code.py
