title: Numpy doesn't provide an attribute
body: <p>I've tried to import a model on Kaggle:
  <code>from statsmodels.tsa.arima.model import ARIMA</code>
  but it returned this error:
  <code>AttributeError: module 'numpy.linalg.lapack_lite' has no attribute '_ilp64'</code></p>
  <p>There's numpy version 1.18.5. Could you please tell how to fix this error?</p>
