Can I run Processing.org Python sketch from a Jupyter Notebook and pass data?

I was looking for a way to run "Processing in Python" scripts out of Jupyter notebooks so I installed calysto_processing. Then I discovered it wants to speak Javascript but I wanted to stay in Python. I want to launch and feed a sketch so the user can change the POV as the data loads, changes, etc.

import numpy as np
import processing as pg

aData = np.load("myDataFile",...)

sketch = pg.launch("mySketch")

while True:
    sketch.update(aData.getNextBatch())
