Package Management

• Install pip: necessary for Windows and some versions of python
  • Test by running pip install virtualenv
  • Make a file that lists your pip packages requirements.txt
    • Create: pip freeze > requirements.txt
    • Install the packages: pip install -r requirements.txt
• PyPI: Python package manager that makes stuff easier, installed with pip install package
  • Note: for some versions above version 3, you need pip3
• virtualenv: creates a micro instance of python with its own pip packages, python version, etc. here's a great doc explaining setup

python -m venv myvenv

Packages

• PILlow: simple image processing library. It is the successor to Python Imaging Library (PIL), so DON'T USE PIL
• scikit-image: advanced image processing library
• OpenCV: great for making intense image processing easy, machine learning. Also works with Java, C++, C
• PyGame
• TensorFlow: Google's machine learning engine. It's in its infancy, but will probably become the new standard for machine learning. Also works with C++
• scikit-learn: machine learning algorithm
