pycharm code autocomplete work only in python console but not on python file

Question

I'm using pycharm IDE, and several libraries such as scikit-learn and pandas. For some reason, if I create a new python file and do:

import pandas as pd
import numpy as np
import matplotlib.pyplot as plot
pd.   #no auto complete here

right after i type pd. auto complete doesn't seem to work. I'm getting nothing. However, if i run a python console within PyCharm, and do similar thing above, the console would pop up an autocomplete window showing all the members of pd..

how do i get autocomplete to work on the main python file?

Answer 1

I used to have this same problem. This was only happening for me in Linux. (I am using python 2.7)

I have since been able to fix it, I think what did it was defining the correct interpreter not only in the running/debugging configuration, but also in the defaults of the project (check File-->settings-->Project Interpreter and File-->default settings-->Project Interpreter)

I have now moved to the next problem, which is that auto-complete works for Python Console and File editing, but weirdly enough does not work for Debugging!...
