Environment:

I have been running an experiment with the ACCESS-ESM1.5 without problem, but 100 years into it, it does not want to run anymore. I get the error:

[ERROR] 'Experiment' object has no attribute 'repeat_run'

Hi @LaurieM, it looks like there’s a bug in the latest version of payu (1.3.6) which affects ESM1.5. We’ll work on getting a fix out for the newest version of payu as soon as possible, but for the moment you should be able to run your experiments by loading payu version 1.3.5:

module use /g/data/vk83/modules
module load payu/1.3.5

I’ll let you know when a new version of payu has been released which fixes the issue.

Thanks Spencer! That seems to fix the issue!
