python dev environment

[geomat0101]

I've moved this over to the python module README. This content is out of date.

This assumes python3 and virtualenv / virtualenvwrapper are installed and configured properly

Initial virtual environment setup

• mkvirtualenv mediamgr
• workon mediamgr (fyi you're going to want to configure vscode to use this venv at some point too)
• pip install ffmpeg-python jsonschema numpy python-arango

System cuda / dlib dependencies (if not installed already)

• cuda (GPU) support: install cuda keyring
• sudo apt install libx11-dev, cuda, libcudnn8-dev

Build / Install dlib

• git clone https://github.com/davisking/dlib
• cd dlib/
• python setup.py install
• read the top of the build output where it's performing installed software checks. Abort the build and install system packages if anything is missing (blas, lapack, ffmpeg, etc. Individual symbols not found are ok and normal, but if it tells you you're missing an installed system package go fix it). If the build completed, use pip remove dlib to nuke it. rm -rf the dlib/build directory and restart the build to try again.
• run the example in mediamgr/python/examples

The output of pip list should look like this:

(mediamgr) mdg@ftl:~/src/mediamgr$ pip list
