在zeppelin的python解释器中无法发挥功能

Question

我可以在python shell中正确运行以下代码，但无法在zeppelin python解释器中运行它。这是zeppelin的python解释器的实现。 https://github.com/zjffdu/zeppelin/blob/master/spark/src/main/resources/python/zeppelin_pyspark.py

有没有人可以帮助我理解为什么泡菜在zeppelin python解释器中不起作用？感谢

代码

def f():
    "hello"

import pickle
pickle.dumps(f)

输出

Fail to execute line 5: pickle.dumps(f)
Traceback (most recent call last):
