iris.pandas.as_series() started throwing error

[luke-wemc]

As of yesterday, when I try and convert a 1d cube to pandas series using iris.pandas.as_series(), I suddenly started getting the following error:

'real_datetime' object has no attribute 'nanosecond'

This was working fine until yesterday, I'm guessing it broke when I updated some packages.

Does anyone have a quick workaround for this? Somehow changing the nanoseconds in the cube to 0 possibly? I'm getting desperate here!

As a very quick guess, I reckon this is due to the latest cftime version (specifically I think at v1.0.2), which introduced nanosecond time accuracy. This is causing problems with Iris master as well.

If you run conda install cftime=1.0.1 does the problem go away?

In fact, here's exactly that error being reported by the Iris tests on Travis. This went away once the Iris build was pinned to not use cftime v1.0.2.1, so hopefully doing the same will fix this problem for you too!

Thanks for the quick reply! This worked in the end:

conda install -c conda-forge cftime=1.0.1

Phew!

Excellent news! Glad things are working again now 👍 I'm going to close this issue now as I think we've got there with solving the problem you reported.

Thanks again though for raising this issue, and please do get in contact again if you encounter other difficulties or things that could be improved 🙂
