x0 is infeasible.

[jaha2600]

I am trying to use pykrige to create an Ordainary Kriged map from a point shapefile.
There are a few rows in the point shapefile that have 'inf' values that I remove at the start of the script, leaving a complete point shapefile.

I import the shapefile and boundary shapefile, create testing and training datasets, and create a 100 by 100 grid succesfully.
However, when I go to create the Ordainary Kriging object I get the below error:

Could I get any advice as to why this is happening?
I attach my complete code to the message.
