我在jupyter上使用pyspark时遇到了一些问题

Question

加载文件时出现的问题。

from pyspark.ml.classification import NaiveBayes  
from pyspark.ml.evaluation import MulticlassClassificationEvaluator 
import pyspark
from pyspark.sql import SparkSession

spark = SparkSession.builder \
         .appName("Mytest") \
         .config("spark.some.config.option","some-value") \
         .getOrCreate()
# Load training data  
data = spark.read.format("libsvm").load("/test/test.txt")
