Source: scikit-learn Version: 0.23.2-5 Severity: serious User: debian...@lists.debian.org Usertags: flaky timeout
Dear maintainer(s),I looked at the results of the autopkgtest of you package because of the recent issues we had with the package not migrating. I had already put it on the ci.d.n reject list for amd64, armel and armhf a while ago intending to file this bug already earlier. Today I removed the block for amd64 to give the fresh upload a try. However, the autopkgtest fails when run on ci-worker13, which is our powerful amd64 worker. That worker has 64 cores and 256GB RAM, while the other amd64 workers have only 2 cores and 8GB RAM. Also our armel and armhf workers are powerful 16 resp. 160 cores and 26GB resp. 511 GB RAM. I have copied an example of a failing test below, but note that not all timeouts happen on the same location.
Because the unstable-to-testing migration software now blocks on regressions in testing, flaky tests, i.e. tests that flip between passing and failing without changes to the list of installed packages, are causing people unrelated to your package to spend time on these tests.On top of that, when a test just hangs that's not good for our infrastructure.
Don't hesitate to reach out if you need help and some more information from our infrastructure.
