nyoka export issue

[saritpg]

Hello,

Here is the example that is given in nyoka github page:

#--------------------------------------------
import pandas as pd
from sklearn import datasets
from sklearn.pipeline import Pipeline
from sklearn.svm import SVC

iris = datasets.load_iris()
irisd = pd.DataFrame(iris.data,columns=iris.feature_names)
irisd['Species'] = iris.target

features = irisd.columns.drop('Species')
target = 'Species'

pipeline_obj = Pipeline([('svm',SVC())])

pipeline_obj.fit(irisd[features],irisd[target])

from nyoka import skl_to_pmml

skl_to_pmml(pipeline_obj,features,target,"svc_pmml.pmml")

#-------------------------------------------------

And here is the error:
