import statsmodel keeps sending up error

[Jun C.]

I am setting up Rodeo with a few imports for the first time as newbie to python:

import sys
import pandas as pd
import pylab as pl
import numpy as np
import statsmodels.api as sm

But import statsmodels keeps giving errors. Here is the latest one:

>>> import statsmodels.api as sm
ImportError: cannot import name '_representation'

It is suspected that there may be circular import within statsmodels that prevents proper setup of

the module namespaces in the right order. Any idea about fix? Many thanks.
