Functions to translate datasets to python library formats (e.g., Pandas, TensorFlow)

[okennedy]

Pain point: Using NumPy/Pandas presently requires writing code to translate datasets to/from standard python frameworks.

Suggested Fix:
The ideal fix would be one that provides native access to each format and (ideally) allows data transfer to happen outside of python... However, a simple, functional solution would be to simply import the data into python and then export it into the native representation.

Progress

• Export to Bokeh
• Export dataset to Pandas dataframe
• Export column to NumPy
• Export dataset to TensorFlow dataset
• Import dataset from Pandas dataframe (e.g., on save)
• Import dataset from NumPy (e.g., replace column?)
• Import dataset from TensorFlow dataset
