Module/attribute problem within Eccodes module

[Jeremy Corner]

I'm trying to use Eccodes in opening a file and I get this error message:

AttributeError Traceback (most recent call last)

AttributeError: module 'pyeccodes.compat' has no attribute 'codes_grib_multi_support_off'

Here is my line of code:
ds = xr.open_dataset(os.path.join(pathfiles,datafile), engine='cfgrib')

Not sure if it's a bug or just using pip instead of conda to install cfgrib as well as Eccodes. I tried to use conda but it wouldn't install in the base environment.

@jcorner1 this is a tricky one, cfgrib didn't yet announce compatibility with eccodes-python and the use of CFGRIB_USE_EXTERNAL_ECCODES_BINDINGS is experimental. And in fact the support is broken starting from version 0.9.8.2. Please use version 0.9.8.1 for now.

@shahramn I should have finally solved the MULTI-FIELD message issues but I needed to use a number of internal interfaces. Now is a good time to sync up.

I'll review the latest version of eccodes-python and report back here.

@alexamici That did indeed fix the issue I was having. Thanks!
