Topic: ✔ plotting using DatetimeGregorian?

I've been suddenly getting this error when I try to plot a single grid cell (grabbed with a .sel method)

float() argument must be a string or a number, not 'cftime._cftime.DatetimeGregorian'

my .time coordinates are:

array([cftime.DatetimeGregorian(2000, 1, 1, 0, 0, 0, 0, has_year_zero=False),
       cftime.DatetimeGregorian(2000, 2, 1, 0, 0, 0, 0, has_year_zero=False),
       cftime.DatetimeGregorian(2000, 3, 1, 0, 0, 0, 0, has_year_zero=False),
       ...,
       cftime.DatetimeGregorian(2049, 10, 1, 0, 0, 0, 0, has_year_zero=False),
       cftime.DatetimeGregorian(2049, 11, 1, 0, 0, 0, 0, has_year_zero=False),
       cftime.DatetimeGregorian(2049, 12, 1, 0, 0, 0, 0, has_year_zero=False)],
      dtype=object

And I read in the full dataset using: 

ds = xr.open_mfdataset(files, combine='nested', concat_dim='time', parallel=True,
                       preprocess=functools.partial(preprocess, varset=varset))
ds['time']   = xr.cftime_range(str(2000), periods=12*50, freq='MS') #fix time bug

Any help would be much appreciated!

nevermind I fixed this by importing nc_time_axis!
