geoplot: axis limits cannot be nan or inf

I am trying to plot a geodataframe with geoplot, and cannot work out the solution to ValueError: Axis limits cannot be NAN or Inf

Context:

Linux (Ubuntu 19.10, x86_64)

cugdf.head():

    Cu_ppm  geometry
0   26.1    POINT (410897.000 7089554.000)
1   31.5    POINT (410896.000 7089604.000)
2   31.3    POINT (410896.000 7089654.000)
3   48.6    POINT (410897.000 7089704.000)
4   32.3    POINT (410896.000 7089754.000)

cugdf.info():

# getting rid of nan and inf values in pandas dataframe
cudb.replace([np.inf, -np.inf], np.nan)
cudb.dropna(inplace=True)
# capturing null values in converted geodataframe
cugdf.isnull().values.sum():

0

The geodataframe plots quite nicely through geopandas, using

cugdf.plot()

I cannot, however, figure out how to plot the same geodataframe through geoplot. Here is the stack trace to the error:

gplt.pointplot(cugdf):

ValueError: Axis limits cannot be NaN or Inf

I’m clearly missing something but I can’t figure it out…
