pyspark错误 - ImportError：没有名为types的模块

Question

我一般都是pyspark和python的新手，当我尝试导入类型模块时，我不断收到此错误：

from pyspark.sql import SQLContext
from pyspark.sql.types import *

我明白了：

`ImportError                               Traceback (most recent call last)
 <ipython-input-9-d10338475100> in <module>()
  1 from pyspark.sql import SQLContext
  ----> 2 from pyspark.sql.types import *

ImportError: No module named types`
