这个 lrModel = lr.fit(training) 有什么问题，它给 Py4JJavaError: An error occurred while call o41.fit

如何解决这个 lrModel = lr.fit(training) 有什么问题，它给 Py4JJavaError: An error occurred while call o41.fit

这个lrModel = lr.fit(training)有什么问题？

import pyspark

from pyspark.sql import SparkSession
from pyspark.ml.classification import LogisticRegression
spark = SparkSession.builder.config("spark.some.config.option","some-value").enableHiveSupport().getorCreate()

training = spark.read.format('libsvm').load('sample_linear_regression_data.txt')

lr = LogisticRegression()

lrModel = lr.fit(training)

错误：

: org.apache.spark.SparkException: Classification labels should be in [0 to -1]. Found 501 invalid labels.
