我在做的工作。今天，当我进入环境，IPython中无法运行，并出现以下错误：IPython的突然打破了畅达的环境中，一个畅达的环境无法导入uniq_stable

ImportError: cannot import name uniq_stable
IPython的是最新的：
ipython 5.3.0 py27_0
似乎在正确的地方进行搜索：
$ which ipython
~/miniconda3/envs/umiopy/bin/ipython
我使用畅达4.3.14。
我没有在环境改变什么，但它可能事情已经由系统管理员更新（虽然这是很难理解怎么会影响我的环境）。什么可能导致这个问题？对于StackOverflow类似的错误，似乎我需要通过conda更新一些模块。
