If this is a Jupyter notebook, you will want to put each snippet of code in its own cell and execute them as you go to see the output. import numpy as np import matplotlib.pylab as plt import uproot import awkward as ak

As a last update (in this sprint, at least), I've released Uproot 4.1.1 (PyPI) with several writing-related performance bugs and one bug-bug fixed, all in PRs #426 and #428. The GitHub pages have some measurements with the code used to make them. A rule of thumb that comes out of this is that you want to call TTree.extend with no less than about 100 kB per array branch. At that point, the Pythonic overhead for writing TBasket metadata is in the noise:
