Since then I haven't heard much about specific problems. The current status for statsmodels on Debian machines is pretty mixed. In several of them some dependencies are not available, in some cases we have errors that might be caused by errors in dependencies, e.g. cvxopt. ppc64el test run for statsmodels has a large number of failure but checking scipy, it looks like it's also not working properly https://buildd.debian.org/status/fetch.php?pkg=python- scipy&arch=ppc64el&ver=0.18.1-2&stamp=1477075663&raw=0 In those cases it would be impossible to start debugging, if we would have to debug through the entire dependency chain. CI-testing for Windows, Apple and Linux for mainly x64 seems to be working pretty well, with some delays while version incompatibilities are fixed. But anything that is not in a CI testing setup looks pretty random to me. (I'm mainly curious what the status for those machines are. I'm not really eager to create more debugging work, but sometimes failures on a machine point to code that is "fragile".)

It looks like even for the release-critical ones, it's just the build that has to succeed and failures are not detected? For example, armel is green but has 9 failures: https://buildd.debian.org/status/fetch.php?pkg=python-numpy&arch=armel&ver=1%3A1.12.0-2&stamp=1484889563&raw=0 Ralf ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org https://mail.scipy.org/mailman/listinfo/numpy-discussion
