One of my runs crashed with this error, have you seen something like this? @bearpelican

@yaroslavvb
Did an old file somehow get run? I had refactored the dataloader so that that line is no longer called
afb8bfb#diff-75be79d6640e3bb96c7683235830b933L307

aha
training is baked into pytorch.v7 AMI, and my task.upload(training) fails silently when directory is present so we end up with old version

gonna fix the upload

[Andrew Shaw]

I'll try to make sure to delete all the training stuff on the next AMI version

false alarm, upload works as expected, the issue was that my refactored version used script version from ~ instead of ~/training
