我尝试通过终端卸载并重新安装numpy，scipy，pandas，patsy和scipy。

我已经通过help（modules）检查了模块，起初得到了Shimwarning

(//anaconda/lib/python3.4/site-packages/IPython/kernel/__init__.py:13: ShimWarning: The `IPython.kernel` package has been deprecated. You should import from ipykernel or jupyter_client instead.
  "You should import from ipykernel or jupyter_client instead.", ShimWarning)

但是，重新安装后，我不再收到此警告，但是，当尝试从statmodels.graphics.tsaplots导入plot_acf时，仍然出现相同的错误

有人可以帮我吗？
