我是pyspark的新手。我在试着运行pyspark代码。我运行了一个名为“time.py”的代码，因此pyspark现在无法运行。我得到下面的错误。

Traceback (most recent call last):
  File "/home/VAL_CODE/test.py", line 1, in <module>

错误在于脚本“/usr/lib64/python2.7/threading.py”引用的是我创建的本地脚本“/home/val\u code/time.py”。现在，我已经删除了“/home/valu code/time.py”脚本。但是当我运行一个新代码“/home/valu code/test.py”时仍然面临这个问题。请帮忙解决。
