no attribute 'MAX_RUN'

[awells96]

Hi,

I'm trying to calculate the longest run of precipitation exceeding 1 mm/day. I found this example in the docs: https://scitools-iris.readthedocs.io/en/stable/generated/api/iris/analysis.html#iris.analysis.MAX_RUN

For example:

The longest run of days with precipitation exceeding 10 (in cube data units) at each grid location could be calculated with:

result = precip_cube.collapsed('time', iris.analysis.MAX_RUN,
function=lambda values: values > 10)

However, when I try this I get the following error
AttributeError: module 'iris.analysis' has no attribute 'MAX_RUN'

I don't get this error with any of the other aggregator instances that I've tried.

Thanks in advance for your help!

Hi @awells96, thanks for getting in touch. iris.analysis.MAX_RUN was introduced fairly recently - Iris v3.3 - so there is a chance that your environment is simply using an older version of Iris.

What version of Iris do you get when you run the following in the command line?

python -c "import iris; print(iris.__version__)"

Hi, that was the problem! My environment was using 3.2.1. It's been updated now and it working as expected - thanks so much for your help!
