hello cloudera community,

 

I'm having trouble using python in zeppelin, when I run a simple script it returns the error below:

Could help to solve this problem?

 

PS¹: script simple:

 

%python

number1 = 2
number2 = 2
total = number1 + number2
print(total)

 

PS²: zeppelin was installed by cloudera manager, version 7.6x, cdp version 7.1.x
