我正在用下面的代码运行pycharm中的python文件。我面临着同样的问题，当我给Pypark在cmd以及pycharm，有人能帮我这个。提前谢谢。
代码：

from pyspark.sql import SparkSession
from pyspark.sql.types import StructType, StructField, StringType, DateType, DecimalType, IntegerType
spark = SparkSession.builder.master("local[*]").appName("ETL").getOrCreate()
spark.sparkContext.setLogLevel("WARN")
source_data_file = "C:\Python_pgms\apache-spark-etl-pipeline-example-master\apache-spark-etl-pipeline-example-master\data\20160104\*"
print("Fetching")

面对以下问题：

Traceback (most recent call last):
