Pycharm does not show recommendations

I have a class called myDevice and it looks like this:

from FeaturesetAlpha import FeaturesetAlphaWrapper

class MyDeviceWrapper:
    def __init__(self, cs_object):
        self.cs_object = cs_object
        self.alpha = FeaturesetAlphaWrapper(cs_object.alpha)

When I create a new devicewrapper and try deviceWrapper. It does not show alpha. when I say deviceWrapper.alpha it works, but do you know why it does not show recommendations? I am using python.
