It seems jedi's bug.

A minimal working example is 1. Save following as example.py ```python import traceback

class ExampleClass(object): def init(self): pass

@property
def value(self):
    print('value called')
    print(traceback.print_exc())

2. In IPython, dopython In [1]: import example

In [2]: ex = example.ExampleClass()

In [3]: ex.val -> press [Tab] value called Traceback (most recent call last): None KeyError: (('value',), frozenset()) File "/home/keisukefujii/anaconda3/envs/tensorflow/lib/python3.5/site-packages/jedi/cache.py", line 119, in wrapper return dct[key] File "/home/keisukefujii/anaconda3/envs/tensorflow/lib/python3.5/site-packages/jedi/cache.py", line 46, in wrapper return getattr(self, name) value called None AttributeError: 'CompiledName' object has no attribute '_infer' Traceback (most recent call last): ```
