Question

我应该如何为Anaconda Python 3.6修复此问题？

/Users/mona/anaconda/lib/python3.6/site-packages/IPython/config.py:13: ShimWarning: The `IPython.config` package has been deprecated since IPython 4.0. You should import from traitlets.config instead.

CTRL +输入上面的代码后出现以下错误：

nat-wireless-eduroam-guest-153-28:CS460_660 mona$ conda install relation_algebra

另外，我找不到relation_algebra包：

Answer 1

这是因为relation_algebra.py应该从relation_algebra.py

下载

ShimWarning：自IPython 4.0以来，不推荐使用`IPython.config`包。您应该从traitlets.config导入
