[Vision] Run Jupyter notebook and re-train TF model

[OscarSmiley]

The software team has decided to use TensorFlow models with OpenCV and Jetpack for computer vision. Previously we created a Jupiter notebook to train vision models. Clone and debug this notebook so it runs locally and use it to train a proof of concept model.

It may be easier to use one of the machines in ELW B250 to train the model if computing time becomes a problem.
