About build / compile of pytorch source on official site

Recently, we haven’t seen a completely successful compile of
pytorch source on official site https://github.com/pytorch/pytorch
for a while (at least for 3 weeks, can check results in
or https://ezyang.github.io/pytorch-ci-hud/build/pytorch-master ).
Is it possible that this is caused by a hardware failure? Say,
memory error?

No. It’s just that certain CI build has problems. If you click on to the build, you can see most builds compile and test fine, e.g. https://ci.pytorch.org/jenkins/job/pytorch-master/4315/

Thanks for the reply. What is CI build?
