我正在尝试运行此代码:

import pyspark
from pyspark.sql import SparkSession

spark = SparkSession.builder \
        .master("local") \
        .appName("Word Count") \
        .getOrCreate()

df = spark.createDataFrame([
    (1, 144.5, 5.9, 33, 'M'),
    (2, 167.2, 5.4, 45, 'M'),
    (3, 124.1, 5.2, 23, 'F'),
    (4, 144.5, 5.9, 33, 'M'),
    (5, 133.2, 5.7, 54, 'F'),
    (3, 124.1, 5.2, 23, 'F'),
    (5, 129.2, 5.3, 42, 'M'),
   ], ['id', 'weight', 'height', 'age', 'gender'])

df.show()
print('Count of Rows: {0}'.format(df.count()))
print('Count of distinct Rows: {0}'.format((df.distinct().count())))

spark.stop()

并得到一个错误
