# This Dockerfile creates a debug helper base image for Python.
# It provides installations of debugpy, ptvsd, pydevd, and pydevd-pycharm
# for Python 2.7, 3.5, 3.6, 3.7, 3.8, and 3.9.
#   - Apache Beam is based around Python 3.5
#   - Many ML/NLP images are based on Python 3.6
#
# debugpy and ptvsd are well-structured packages installed in separate
# directories under # /dbg/python/lib/pythonX.Y/site-packages and
# that do not interfere with each other.
#
# pydevd and pydevd-pycharm install a script in .../bin and both install
# .py files directly in .../lib/pythonX.Y/site-packages.  To avoid
# interference we install pydevd and pydevd-pycharm under /dbg/python/pydevd/pythonX.Y
# and /dbg/python/pydevd-pycharm/pythonX.Y
