Problem importing Iris in Google Colab

[Matthew Grant]

I am wanting to use Iris in Google Colab, however I am having difficulty getting it imported. I have managed to install it through Conda, however when I import it, it returns the following error message:

ImportError                               Traceback (most recent call last) <ipython-input-24-089b5db944e7> in <module>() ----> 1 import iris

6 frames

/usr/local/lib/python3.6/site-packages/cf_units/__init__.py in <module>()      43 from .util import _OrderedHashable, approx_equal      44  ---> 45 from cf_units import _udunits2 as _ud      46 from cf_units._udunits2 import (UT_ASCII, UT_ISO_8859_1, UT_LATIN1, UT_UTF8,      47                                 UT_NAMES, UT_DEFINITION) ImportError: cannot import name '_udunits2' from 'cf_units' (/usr/local/lib/python3.6/site-packages/cf_units/__init__.py)

I have checked and both cf_units and _udunits2 are installed, however it seems colab is struggling to identify _udunits when importing it. Does anyone know a way to fix this? Or, is there another way to install and import Iris in Google Colab without coming across this issue?

Thanks very much in advance!
