我正在尝试使用以下代码安装spark会话：
#Initialize SparkSession and SparkContext
from pyspark.sql import SparkSession
from pyspark import SparkContext
#Create a Spark Session
SpSession = SparkSession \
.builder \
.master("local[2]") \
.appName("V2 Maestros") \
.config("spark.executor.memory", "1g") \
.config("spark.cores.max","2") \
.config("spark.sql.warehouse.dir", "file:///c:/temp/spark-warehouse") \
.getOrCreate()
#Get the Spark Context from Spark Session
SpContext = SpSession.sparkContext
我收到以下错误：
SpSession = SparkSession \
.builder \
.master("local[2]") \
.appName("V2 Maestros") \
.config("spark.executor.memory", "1g") \
.config("spark.cores.max","2") \
.config("spark.sql.warehouse.dir", "file:///c:/temp/spark-warehouse") \
.getOrCreate()
Traceback (most recent call last):

请帮忙。新的火花。我正在使用64位系统，运行python 2.7。

我有同样的问题。对于将来阅读此内容的任何人，我能够通过从桌面快捷方式启动Spyder IDE来解决此问题，而不是从Anaconda命令提示符（Windows 7 64位）执行spyder。
