python-2.7 - pandas ols 导入损坏？

Question

我尝试在 pandas 0.9.1 中执行 OLS，但出现此错误:

ipdb> foo = ols(y=df[y_var[1]], x=df[x_var], pool=False )
*** ImportError: No module named scikits.statsmodels.api

我猜错误来自ols.py:

try:
    import statsmodels.api as sm
except ImportError:
    import scikits.statsmodels.api as sm

这是否意味着我错误地安装了pandas？

@TomAugspurger 来救援:

statsmodels is a separate package that is an optional dependency for pandas. You'll need to install statsmodels to do OLS. Try pip install statsmodels. You'll probably want to install the development build. I think they're close to releasing a new version so it should be very stable. – TomAugspurger 2 hours
