right now I only did miniforge (though our elder
python environments are anaconda or conda). And:
Yes, the env was activated and no other xarray
or cfgrib stuff around here. :-)
When I create a complete new miniforge3-4.9.2-3
on our system and only do a
conda install eccodes
conda install cfgrib
the thing works. So there must be some relicts
from earlier package installs or some other
versions that cause the trouble. I got some
hints from a different site that it might even
be dependent on the order in which things are
installed, not sure about that. Still I wonder
that the error message seems to imply that
there might be a circular import...
I'll do some further testing and will come
back when I have something that is more
concrete so that you can look at it.
Thanks, Olaf

Well, just to narrow down the error: I guess a working ""import cfgrib"" would be the precondition for it to work with xarray... (?)","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,856915051

Hi keewis and aurghs, as the working version with cfgrib 0.9.8.5 is already in production, it took some time to reproduce the previous environment from a backup. So here we are. Versions are:
% conda list | egrep ""(cfgrib|xarray|eccodes)""
cf_xarray 0.3.1 pyhd3deb0d_0 conda-forge
cfgrib 0.9.9.0 pyhd8ed1ab_1 conda-forge
eccodes 2.21.0 ha0e6eb6_0 conda-forge
python-eccodes 2021.03.0 py38hb5d20a5_1 conda-forge
xarray 0.16.2 pyhd8ed1ab_0 conda-forge
With ""xr.tutorial.open_dataset(""era5-2mt-2019-03-uk.grib"", engine=""cfgrib"")"" the result is the same, error message is:
AttributeError: partially initialized module 'cfgrib' has no attribute 'open_file' (most likely due to a circular import)
Full error output is attached. And I attached the output of ""xr.show_versions()"". I wonder why it shows ""cfgrib: None""...
Cheers, Olaf
