getting error which classification with text label

[vrunda-joshi]

Hi,
I am looking for the code where i can predict multiclass classification.
I have trained code in m.net and predicting in python using nimbusml.
here is my sample code.

AirQualityClassification.zip

"
import pandas as pd
from nimbusml import Pipeline
p = Pipeline()
p.load_model("/dbfs/FileStore/tables/AirQualityClassification.zip")
ds = pd.read_csv('/dbfs/FileStore/tables/Testing_Data.csv')

score = p.predict(ds,y='Status',evaltype='multiclass')

"
Getting error: 'Could not apply a map over type 'String' to column 'Status' since it has type 'Double''
Testdata csv
