Quería usar los siguientes pandas, pero no pude importarlo en absoluto.

https://github.com/pydata/pandas/releases/download/v0.15.0/pandas-0.15.0.win-amd64-py2.7.exe

Sin embargo, no pude importarlo:

import pandas as pd

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import pandas as pd
  File "C:\Python27\lib\site-packages\pandas\__init__.py", line 45, in <module>

    self.component_re.split(vstring))

¿Qué pasa chicos?
