3. JupyterHub

Running the import_config_esgf.ipynb notebook on kitware.2i2c.cloud triggers this error.

    TypeError: <class 'cftime._cftime.Datetime360Day'> is not convertible to datetime, at position 0

The cloud version is using release 0.8.8, so we need a new release once this is fixed.

I think the only bug was my naivete. Once I updated to the current pyvista-xarray, the problems loading this data were resolved. And my guess is that the JupyterHub instance will work once we update its container image.
