Spyder报错：IPython console无法启用，报错An error ocurred while starting the kernel

遇到问题

1. 我在win7（64bit） 安装了最新的annaconda，安装启用了默认环境spyder3.3.2后遇到了如下问题：

  	
File "E:\Anaconda3\lib\site-packages\traitlets\traitlets.py", line 528, in get
  value = obj._trait_values[self.name]
KeyError: 'context'

Traceback (most recent call last):

File "zmq/backend/cython/context.pyx", line 49, in zmq.backend.cython.context.Context.__cinit__
zmq.error.ZMQError: Unknown error
Traceback (most recent call last):

2. 解决上述问题后，我新建了一个包含opencv的新环境，并安装启用了spyder3.3.3后又遇到了如下问题：

Traceback (most recent call last):
File "E:\Anaconda3\envs\CvDlib\lib\site‑packages\traitlets\traitlets.py", line 528, in get
value = obj._trait_values[self.name]
KeyError: 'context'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

探寻问题的原因

我们使用pyCharm启动，会产生如下提示：

Cannot start internal HTTP server. Git integration, JavaScript debugger and LiveEdit may operate with errors. Please check your firewall settings and restart PyCharm

感谢flyfish1986的答案，错误原因是防火墙。

PS：问题2产生的原因是新加了opencv库（或者说是附加库），导致windows防火墙对程序通讯的阻碍。

解决方法

方法一：

windows防火墙允许以下程序
E:\Anaconda3\pythonw.exe
E:\Anaconda3\pytho.exe
通过防火墙，spyder3.3.2中的IPython即可运行成功！！！

方法二

由于安装了其他库，导致问题2产生，所以关闭了Windows防火墙，该问题消失。
spyder3.3.3中的IPython也可运行成功！！！
