Platforms

Linux makes up over 99.9% of all searches so I’ve discounted the rest. Raspberry Pi OS and Debian are now combined (due to Raspberry Pi OS identifying itself as Debian). This group obviously dominates with over 98%. Ubuntu remains in third place with only 0.7%, although we don’t officially support it.

The latest OS release, Bullseye, has taken a sizeable chunk of the share (25%), but it’s far from taking over Buster (68%), due to compatibility issues with e.g. picamera. Stretch has dropped to under 7% and there’s practically no Jessie usage.

armv7l (Pi 2/3/4 – and now Zero 2) is still a majority architecture with 95% of searches from Arm devices (89% of which is from armv7l). Last quarter we saw more hits from aarch64 users than x86_64 and armv6l combined, but this spike has diminished, although aarch64 still (just) beats armv6l, with 4.6% to 3.5%:

Python 3 has an overwhelming majority of usage (88%), and 3.7 (the version provided by Buster) has the highest share with 54%. Bullseye’s Python 3.9 now comes second with 24% and Python 2.7 comes third with 15%:

We’re also logging pip and setuptools versions:

We see over 5TB of bandwidth each month, peaking at 5.54TB in November. The breakdown of bandwidth in the period is 79% pip downloads, 2.5% pip searches, a tiny amount (0.09%) of website traffic (project pages, JSON, etc) and the rest (surprisingly high, 17.5%) comprising mostly of direct wheel downloads not from pip (e.g. browsers):
