aaronmarkham opened a new issue #13410: ARM QEMU test in CI failed unrelated PR
URL: https://github.com/apache/incubator-mxnet/issues/13410
 
 
   ## Description
   Test with ARM QEMU fails with some kind of network interruption...
   
   Makes wonder about these network issues where dependencies fail to download... should we put in a retry function, so that we don't have to restart our PRs when there's a transient error?
   
   ## Error
