IPython console error in Spyder 3.0.0b3

Description of your problem

When I want to call any function and type the left bracket in ipython console, the error message will prompt in internal console. The error message is as below:

Traceback (most recent call last):
  File "/usr/local/opt/pyenv/versions/3.5.1/lib/python3.5/site-packages/qtconsole/base_frontend_mixin.py", line 163, in _dispatch
    handler(msg)
  File "/usr/local/opt/pyenv/versions/3.5.1/lib/python3.5/site-packages/spyderlib/widgets/ipython.py", line 377, in _handle_inspect_reply
    signature = self.get_signature(content)
  File "/usr/local/opt/pyenv/versions/3.5.1/lib/python3.5/site-packages/spyderlib/widgets/ipython.py", line 296, in get_signature
    text = ANSI_OR_SPECIAL_PATTERN.sub('', text)
TypeError: expected string or bytes-like object

What steps will reproduce the problem?

1. For example, we try to call the print('test').
2. To input the print(.
3. the error message will be prompt in the internal console.

How could I solve this problem?

I can confirm this problem was fixed in IPython 5.0 beta3.

@iamsc, please update with this command:

pip install --pre -U ipython
