Hi, I’m interested whether there is a way to get APT repo download stats of all packages, not just the few top packages mentioned on metrics.ros.org. I know this has been discussed before (Data on most popular ROS packages), but with no resolution. @DLu managed to put together the full report once, so I wonder if it’s possible to reproduce it on newer data. I know there are several mirrors out of control of Open Robotics, but even stats from the main APT repo would be interesting.
I’m not sure whether e.g. crawling data like Statistics for packages.ros.org (2022-02) - urldetail would lead to the correct numbers. I’d expect that when a package is updated, there should be at least as many downloads as there are mirrors, but I found packages where this doesn’t hold, so I’m confused about what these numbers mean…
The full report was a result of crawling and parsing the OSU data. It’s by no means a perfect measure of overall usage, but I believe it to be an accurate measurement of downloads.
Great, thanks! I’ve run the analysis for ROS1 packages now, and here are the results: Number of total *.deb package downloads of all released ROS 1 packages (Melodic + Noetic) · GitHub .
Please note this metric tends to give advantage to packages with more built versions, as each download of any version of the package counts.
Interesting that the “deprecated”
tf package has the second highest number of downloads .
My guess -
tf.transformations. That’s just the easiest reachable library for working with quaternions in Python. My second guess - people often do not check
package.xml for removals of dependencies…
